standard of nm450 wear-resistance density

The pipeline steel coil standard of NM450 wear-resistance 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.

We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product standard of NM450 wear-resistance annual capacity is 200 thousand tons.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the standard of NM450 wear-resistance metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between standard of NM450 wear-resistance strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

Our products have perfect after-sales system to protect the interests of customers. At the same time, we can according to standard of NM450 wear-resistance customer's requirements, processing requirements, cutting technical requirements, etc., to develop detailed solutions for customers, so as to make customers 100% satisfied. If you have any requirements and needs, please contact us in time.
