TB stadndard 09CuPCrNi-B bare surface

Standing at a new historical starting point, we adapt to the requirements of supply side TB stadndard 09CUPCRNI-B structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading TB stadndard 09CUPCRNI-B steel materials supplier.

The theoretical weight of seamless steel pipe is the weight per meter of steel pipe calculated by the calculation formula: meter weight = (outer diameter - wall thickness) * wall thickness * 0.02466, in which the outer diameter refers to the farthest distance between the outer walls on both sides of the steel pipe, and the wall thickness is the thickness of the seamless steel pipe wall. The weight per meter of TB stadndard 09CUPCRNI-B seamless steel pipe is calculated by the formula. If you want to get the weight of the whole seamless steel pipe, you should multiply the actual length of the steel pipe.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the TB stadndard 09CUPCRNI-B principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.

TB stadndard 09CUPCRNI-B, A588 GrB steel has high atmospheric corrosion resistance by alloying with Cu, P, Cr and Ni to form a protective layer on the surface of metal matrix. A588 GrB steel is widely used in various weather resistant building structural parts (especially in industrial atmospheric environment), bridge auxiliary structural parts and so on. Chemical composition of A588 GrB steel: C: ≤ 0.20, Si: 0.15-0.50, Mn: 0.75-1.35, P: 0.040, S: 0.050, Cr: 0.40-0.7, V: 0.01-0.10, Ni: ≤ 0.50, Cu: 0.20-0.40.
