Effect of S content fluctuation on mechanical properties of 09CuPCrNi-A hardness

A small amount of Nb is sufficient to obtain excellent comprehensive properties of 09CuPCrNi-A hardness etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.

The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, 09CuPCrNi-A hardness steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and 09CuPCrNi-A hardness carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.

BBN company has implemented a resource strategy combining global resource procurement, domestic resource unified purchase, and joint purchase and distribution. It has maintained good relations of cooperation with more than 100 domestic and foreign steel mills, and can purchase low-quality and high-quality steel futures in all directions and through multiple channels. The company can grasp the specifications and quantities of the spot resources of major steel mills in real time, and can timely and quickly meet customer demand for steel spot resources.

Our company has strict quality control standards. If you want to visit our factory, you are welcome at any time! We produce a lot of steel products every month to export 09CuPCrNi-A hardness to all over the world. Because our customers are from all countries, they will order a large number of steel products from our company every month.
