Low alloy structural steel for welded structures
The company Electrocentury-steel offers to buy in any range of brands and grades of low alloy structural steel for fabrication of welded structures. Are great prices from the manufacturer, ensures prompt delivery of the rental to any place specified by the customer.
Composition
Low alloy structural steel for fabrication of welded structures, in Russia and the CIS countries are produced according to requirements GOST 5058. Their characteristic features are:
- Low carbon content (not more than 0.15%);
- The presence of manganese in the amount of 0.8…of 1.80%;
- The restriction of non-metallic impurities (phosphorus and sulfur) — not more than 0,035%;
- Mandatory presence of Nickel and copper (not more than 0.30%).
The amount of silicon varies depending on the brand of material: from 0.17…0.37 percent for steel 09Г2 to 0,50…0,80% for steel 09G2S.
Foreign analogues of structural steel GOST 5058 are: in Europe — 17Mn4 steel, which is made of German DIN standards and steel grades А515/516 Gr.70, produced by the American steelmaking companies.
Buy low-alloy structural steel for the price from the manufacturer, the company offers Electrocentury-steel. The provider ensures strict compliance with the range of products supplied, and its prompt delivery to the address specified by the customer.
Properties
Depending on their chemical composition (at normal temperatures) of low-alloy structural steel for welding constructions have the following mechanical characteristics:
- Limit strength tensile — 470…670 MPa;
- Yield strength, MPa — 380…520 MPa;
- Hardness Brinell — 165…200 HB.
With increasing temperature the strength characteristics are reduced and the ability of steels to plastic deformation increases.
Buy rolled low alloy structural steel for welding constructions in a wide range of brands and profiles, the company offers Electrocentury-steel. Prices — from the manufacturer. The supplier ensures prompt delivery of products to any destination specified by the customer.
