Effect of S content fluctuation on mechanical properties of mechanical properties of nm300 steel

The company has five major departments: steel plate production department (including quality inspection team), sales department, market development department, after-sales and logistics department, and finance department. The backbone of steel business from all over the country, with the chairman as the core, integrates self-confidence, independence, passion and responsibility, and strives for excellence! All people share the same belief: "Being a refined steel product line rewards customers, strengthen the steel industry, and realize the corporate dream!

EN10025-2 S355JR low alloy steel grade is equivalent to GB Q345B in Chinese standard. For the normal thickness, these two steel grades are both owned 345MPa yield strength. Plate S355JR+N indicates that the S355JR steel plate must be done Normalized heat treatment when rolling for improve the steel strength and weldability. Our mill would roll mechanical properties of nm300 steel, S355JR alloy steel plate under as rolled or control rolled when customers' have not requested any heat treatment in their P/O.

mechanical properties of nm300 steel, No.45 seamless pipe belongs to high quality carbon structural steel. The carbon (C) content of No.45 seamless pipe is 0.42 ~ 0.50%, Si content is 0.17 ~ 0.37%, Mn content is 0.50 ~ 0.80%, Cr content is ≤ 0.25%, Ni content is ≤ 0.30%, Cu content is ≤ 0.25%. The tensile strength, yield strength, elongation, reduction of area and impact energy of No.45 seamless pipe are 600 MPa, 355 MPa, 16% and 40% respectively. No.45 seamless pipe is used to manufacture high strength moving parts.

The tensile strength of seamless steel pipe is more than 8-10 times of that of ordinary steel, and its elastic modulus is better than that of steel, with excellent creep resistance, corrosion resistance and seismic resistance; the mechanical performance of seamless steel pipe is excellent, easy to machine, etc.; the seamless steel pipe mechanical properties of nm300 steel is highly elastic, reused in mechanical equipment, memoryless, deformation free, and antistatic.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel mechanical properties of nm300 steel plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.

Our company is one of the famous steel suppliers in China, specializing in the production of steel plates, steel pipes and other steel products. If you are interested in steel products, or need to purchase a large number of mechanical properties of nm300 steel steel plates and pipes.
