Special Design for Mechanical Seamless Carbon Steel Tube Pipe, Process Steel Pipe Dia 457mm 420mm 380mm 365mm 27simn 45mn2 42CrMo4 Q+T 41cr4
Short Description:
27SiMn steel pipes are widely used in automobile, petroleum, chemical and shipping industries. 27SiMn steel pipe is normalized and tempered, and coated with phosphate inside and outside. This steel pipe is mainly used in the quenched and tempered state to manufacture hot stamping parts (hydraulic parts) requiring high toughness and wear resistance, and hot stamping parts requiring high toughness and wear resistance.
27SiMn seamless steel pipe has high hardenability, the critical hardenability diameter in water is 8~22mm, good machinability, medium cold deformation plasticity and weldability; In addition, the toughness of the steel pipe is not much reduced during heat treatment, but it has quite high strength and wear resistance, especially in water quenching.
Our goal is usually to consolidate and improve the high quality and service of existing solutions, meanwhile continuously create new items to meet unique customers’ requires for Special Design for Mechanical Seamless Carbon Steel Tube Pipe, Process Steel Pipe Dia 457mm 420mm 380mm 365mm 27simn 45mn2 42CrMo4 Q+T 41cr4, Together with our endeavours, our products and solutions have won the trust of buyers and been quite salable the two here and abroad.
Our goal is usually to consolidate and improve the high quality and service of existing solutions, meanwhile continuously create new items to meet unique customers’ requires for China Steel Pipe 41cr4 and Steel Pipe 45mn2, We welcome customers from all over the world come to discuss business. We supply high quality solutions, reasonable prices and good services. We hope to sincerely build business relationships with customers from at home and abroad, jointly striving for a resplendent tomorrow.
