МеталлоторгMetal round bar - full-bodied rolled round cross-section from 5 mm to 350 mm.

round bar production

According to the method of production the rounds are made hot rolled and cold rolled.

Hot rolled steel round bar GOST 2590-88 produced by hot rolling. The surface of the hot-rolled wheel may be ground. And also the rounds get forged according to GOST 1133-71. Depending on the purpose, hot-rolled and forged metal rounds are heat treated.

Cold-rolled or cold-drawn round bar (also known as rod) is a calibrated metal-roll that has a more accurate diameter. It is made according to GOST 7417-75 standard with a diameter of from 3 to 100 mm, smelted in a special way and also processed by the method of cold drawing. As a result of such manufacturing, physical, plastic, mechanical properties of steel, surface characteristics are enhanced. Additional processing gives a polished or matte surface. The round bar calibrated steel in accordance with GOST 7417 can be made of stainless steel, the surface of which is polished to improve the properties of steel. Also, the steel round bar can be subjected to additional galvanization to ensure resistance to aggressive environments and to obtain a galvanized steel round bar

The stainless round bar can be calibrated cold rolled or cold drawn or hot rolled; processed by grinding and with a matte surface. According a degree of curvature stainless steel has a first steel grade and a second.

 

 

Steel wheel application

Steel rounds are often used as a blank for metalware: shaped section and pipe flat rolled stock. The hot-rolled steel round bar is universal, it is used in reinforcement of concrete products as an alternative to steel grade A1 (A240) reinforcement in construction, engineering, shipbuilding and machine-tool construction, heavy industry, automotive, space industry, for the construction and strengthening of road barriers, various metal structures. Different types of fasteners for the needs of the railway are made of hot-rolled wheels: washers, spring terminals, etc. Due to its resistance to adverse conditions, a calibrated round bar has become indispensable in construction in northern latitudes, and it is also used to ground gas lines. Calibrated rounds are widely used in design and outdoor advertising. Stainless steel rounds are used in construction, often for those structures that will be subjected to aggressive conditions - high loads and high temperatures. Calibrated stainless steel range has found its place in the automotive, aviation, shipbuilding, pharmaceutical, food and other industries, in the manufacture of pipes and the manufacture of grinding balls. Made of stainless steel furniture accessories, fences, tools, flanges, bolts, nuts, dishes, shafts and hubcaps, they are used in engineering and metalworking, in the defense industry, in bridge construction and railway industry.

 

Круг стальнойDepending on the diameter of the rounds supplied they have following types:

1. in coils — diameter 6.5 mm - 20 mm
2. in bars - diameter 8 - 350 mm
3. in forgings with a diameter of over 350 mm

By the quality of the surface the rounds have following types of groups:

1. 1GP - 1st surface group: selective round, no surface irregularities
2. 2GP - 2nd surface group: for hot working with pressure, defects on the surface are allowed, which are cleaned with emery
3. 3GP - 3rd group: without stripping, with separate rolled out bubbles, risks. Handled mechanically.

                                   

                               Hot-rolled steel round bar GOST 2590-88

The standard applies to hot rolled round section with a diameter of 5 mm to 270 mm, inclusive, obtained by the method of hot rolling. Large diameter rounds are made according the consumer requirements. Our organization supplies a round bar up to 350 mm and forging a larger diameter. Hot-rolled rounds are valued for their high strength and ductility, the rounds in st3 are well welded, which ensures a high speed in the manufacture of metal structures.

Steel Round Bar Manufacturers:

OAO Oskolsky Electrometallurgical Plant (OEMK), Orsk-Khalilovsky Metallurgical Plant (NOSTA), ZapSib, OAO Metallurgical Plant named after A.K. Serova ", OAO" Severstal ", OAO" Nizhny Tagil Iron and Steel Works "(NTMK), OAO" Nadezhdinsky Metallurgical Plant ", OAO" Trading House VMZ "Red October" Electrometallurgical Plant "Dneprospetsstal" them. AN Kuzmin.

For the manufacture of hot-rolled wheels used steel of different grades, which affects the ability to use them in different industries.

Steels from which hot rolled rounds are made are of following types:

1) Carbon steel of ordinary quality - building steel (St 0 - St5)

Metal rounds of steel 3 are most in demand. round bar steel 3 is in demand primarily in construction, for the manufacture of metal structures, fences, for reinforcement of reinforcement for columns.

2) Low-alloyed quality structural steel (09G2C, 09G2, 10HSND, 30HGSA)

round bar 09G2C steel grade is used in construction in areas with more severe climates, for welded structures, for steam boilers, apparatuses and tanks operating under pressure and at temperatures ranging from - 70 degrees to 450 degrees C. Low-alloy steel differs from construction of greater strength due to the higher yield strength, it is used for critical structures.

3) Constructional quality carbon steel (St08, St10, St15 St20, round steel 25 , St30, St35, St40, St45 - is in demand in engineering.

round bar steel 20 - goes to lightly loaded parts (rollers, stops)..

round bar 35 steel is used for parts experiencing small stresses (axles, thrust, levers, shafts), and round bar 45 steel is used for parts requiring increased strength (axles, toothed rails, shafts, couplings).

4) Tool steel wheels: U8, U8A steel and others are used for the manufacture of critical metal structures, various metal-cutting tools

5) Structural alloyed steel (12XH, 15X, 40X, 50G, etc.)

A round bar 40X steel is used instead of steel 45 for shafts, couplings, etc.

6) Corrosion-resistant heat-resistant steel

Stainless steel round bar , supplied by our company, produced according to GOST 5632, GOST 7417, GOST 4543 and GOST 5949.

Standard 5632 applies to corrosion resistant, alloyed stainless steels and alloys, heat-resistant steels. Stainless steel 12X18H10T is considered to be cryogenic and heat resistant, resistant to solutions of nitric, phosphoric, acetic acids, salts and alkalis. 20Х13 is used in the structure of the furnace and power engineering.

Stainless steel round bar GOST 4543 describes the technical conditions of alloyed structural steel, for example, 25HGT steel, 25HG3A steel grades round bar, 18HGT stainless steel round bar, 20XH3A steel round bar and 20202H4A steel bar, stainless 40HN steel bar, round bar 40HN2MA steel. Chrome-manganese steel 25HGT is used for loaded gears. St12XH3A - for the production of piston pins, shafts, gears, parts, working with shock loads and temperatures up to minus 100 degrees. Steel 18HGT, st20KhN3A, st20H2N4A improve objects in terms of increasing strength and are necessary to withstand shock loads, temperature changes. Steel 40XH2MA is applicable in valves, shafts, connecting rods, bolts, couplings, discs.

Chrome-nickel structural alloyed steel 40XH - for shafts, couplings, bolts, connecting rods, gears, cylinders, and other critical parts.

Specifications of varietal and calibrated corrosion-resistant, heat-resistant and heat-resistant round steel 40X13 are prescribed in GOST 5949. Stainless steel 40X13 is used for bearings, cutting tools, springs, which operate at a high rate of up to 450 degrees C.

GOST 7417 describes a calibrated stainless steel wheel.

7) Spring-spring structural quality steel (50HFA, 60G, 60S2HA, 65G, 70, 75, etc.)

8) Heat-resistant structural quality steel (12MH, 15H5, 20H1M1V1BR, etc.)

9) Special steel for grinding balls (W1, W2, W3)

 

For rolling accuracy, a steel round bar is manufactured:

- A - high accuracy
- B - high accuracy
- In - usual accuracy

round bar steel GOST 2590 88 produce:

– up to 9 mm in diameter - in coils

– over 9 mm - in bars




Depending on the destination, the round bar of GOST 2590 is:

– measured length

– multiple measured length

– unmeasured length

The long round bar of GOST 2590 88 or the round bar of GOST 2590 2006 is made:

– 2 - 12 m - from carbon steel of ordinary quality and low alloy steel

– 2 - 6 m - from high quality carbon and alloy steel

– 1 - 6 m - from high-alloy steel.

Depending on the standardized indicators, round bars have following types of categories: 1, 2, 3, 4, 5. To designate a category, a category number is added to the designation of the steel grade: St3sp1, St3ps3.
