27SiMn Seamless Steel Pipe Hot Rolled Thick Walled Seamless Steel Pipe
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.
We are also focusing on improving the stuff management and QC system so that we could keep great advantage in the fiercely-competitive business for 27SiMn Seamless Steel Pipe Hot Rolled Thick Walled Seamless Steel Pipe, The principle of our organization is usually to provide high-quality items, qualified services, and trustworthy communication. Welcome all friends to place trial order for developing a long-term small business relationship.
We are also focusing on improving the stuff management and QC system so that we could keep great advantage in the fiercely-competitive business for 27simn Alloy Seamless Steel Pipe, We now have our own registered brand and our company is developing rapidly owing to high quality goods, competitive price and excellent service.
