Alloy carbon hardness of nm450 sheet used in construction

According to the separate performance report released by India's Jindal stainless steel (Sisal) Co., Ltd. (JSHL), as of March 31, 2020, due to the global economic slowdown, epidemic situation, imports and other factors, its hardness of NM450 sheet stainless steel sales decreased by about 10% to 600000 tons from 667000 tons in the previous fiscal year, and its net sales decreased by nearly 7% to 83.396.9 billion rupees, with the same gross operating profit (EBITDA) After tax profit increased by 22.4% to 3.203 billion rupees. The adoption of the new tax system has a positive impact of RS 220 million on after tax profits.

Q345E steel plate is a low-alloy high-strength steel plate with good low-temperature impact performance. The steel grade is composed of three parts: Q (Qufu in Chinese spelling) representing yield strength, yield strength value, and quality grade symbol. hardness of NM450 sheet, Among them: Q represents the yield strength; 345 represents the yield strength value, unit MPa; E represents the grade (passed -40 degrees impact test).

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. hardness of NM450 sheet, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.

our company offered 2950 ton A36 steel hardness of NM450 sheet plate to Philippines customer, which was used to build water supply project. It is the government project. The procurement with their project engineer come to China to discuss this project in middle of 2016. After checking the mill, they signed the contract with us. we supply the ASTM A36 Original Mill Test Certificate Stamped.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate hardness of NM450 sheet EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
