Professional low cost of nm500 steel manufacturer in China
India's Ministry of low cost of NM500 steel steel has extended the deadline for steel product certification from April 23 to three months as the Bureau of standards (BIS) has closed factories and laboratories due to the current blockade and travel ban. According to the order of the Ministry of Commerce, "the implementation date of the following Indian Standards is extended for three months after April 23, according to the notice of the order for low cost of NM500 steel steel products 2000."
Between alloy wear-resistant layer and the substrate of wear-resistant steel is metallurgically bonded. Through special equipment and automatic welding process, high-hardness self-shielding alloy welding wire is uniformly welded on the substrate, and the number of composite layers is one to two or even multiple layers. During the compounding process, due to the different alloy shrinkage ratio, uniform transverse cracks occur. It is a distinctive feature of wear-resistant steel plates, low cost of NM500 steel.
T11 steel is a steel grade produced according to American Standard ASTM A213. T11 steel is used for boiler, superheater and heat exchanger tubes with minimum wall thickness. Chemical composition of ASTM A213 T11 steel: C 0.05-0.15, Si 0.50-1.00, Mn 0.30-0.60, P, S ≤ 0.025, Cr 1.00-1.50, Mo 0.44-0.65. Mechanical properties of ASTM A213 T11 steel: tensile strength ≥ 415 Mpa, yield strength ≥ 170 Mpa, elongation ≥ 30%. The main ASTM A213 steel pipe grades are A213 T11, A213 T12, A213 T22, low cost of NM500 steel, etc.
