The business department is mainly responsible for communicating with customers, from the manufacturing of steel plates, steel pipes and other products, knowing customers' needs and processing conditions, etc. within the time agreed with customers, the delivery time is short, the price is the most competitive, and the service is the best. Their responsibilities are to deal with customer consultation, solve customer problems, update production plans, and instruct the logistics department to deliver products to customers.

The pipeline steel coil S275JR chemical composition and plates are our main products. And the most popular standard for pipeline steel is API 5L. We mainly supply API 5L grade B (L245), API 5L X42 (L290), API 5L X46 (L320), API 5L X52 (L360), API 5L X56 (L390), API 5L X60 (L415), API 5L X65 (L450), API 5L X70 (L485) pipeline steel coil and plates. Those stteel grades have both PSL1 and PSL2 levels. PSL2 has more strict requirements than PSL1. Besides, we also supply API 5L grade A PSL1 and API 5L X80 PSL2 steel.

Our S275JR chemical composition, GB/T 1591-2008 Q460D plates are supplied with thickness up to 100mm. Below is our product stock list: 12*1730*8200, 28.58*2172*12100, 22.23*2181*12000, 28.58*2172*12300, 28.58*2171*12100, 35*2200*3500, 22.23*2182*12200, 28*3720*9400, 22.23*2182*12000, 35*2200*3800, 22.23*2125*12000, 24*3000*8850, 22.23*2075*12000, 14*2405*7610, 28.58*2172*12300, 48*2590*7000, 28.58*2172*11400, 75*1800*3500, 120*2040*9150.

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 S275JR chemical composition alloy steel S275JR chemical composition 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.
