India's Ministry of 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 steel products 2000."

Our quality control department will do inspection for details of the steel materials before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.SM490A carbon steel material

Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This 20Cr alloy steel still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.

SM490A carbon steel material,The trend of international shipping development of large-scale ships and strategic joint ventures puts forward higher requirements for modern ports. Modern ports no longer use the general cargo throughput as a measure sign, and container throughput will become the main sign to measure the role and status of modern ports. The average container capacity in 2000 is 3200teu, and it is expected to be 5500teu in 2020.

Due to the existence of this dense oxide film, the infiltration of oxygen and water into the steel matrix in the atmosphere is prevented, the development of corrosion into steel material is slowed down, and the atmospheric corrosion resistance of steel material is greatly improved. Weathering steel is a kind of steel system which can be used thinly, exposed or simply painted, and make products resistant to corrosion, prolong life, save labor and reduce consumption, upgrade and replace.SM490A carbon steel material
