Seamless Alloy Steel Pipe 180*22 180*25 40cr Alloy Tube 4140 Alloy Structure Pipe
40Cr steel is one of the most widely used steels in machinery manufacturing industry. After quenching and tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of the steel is good, and it can be quenched to the maximum when water quenched Ф 28 ~ 60mm, oil quenched to Ф 15～40mm。 When the hardness is 174 ~ 229hb, the relative machinability is 60%. The steel is suitable for making medium plastic mould.

Straight welded pipe ERW thin wall tube
Welded steel pipe, also known as welded pipe, is a steel pipe welded with steel plate or strip steel after crimping. Generally, the length is 6m. Welded steel pipe has the advantages of simple production process, high production efficiency, many varieties and specifications and less equipment investment, but its general strength is lower than that of seamless steel pipe. Welded pipes with large or thick diameter are generally made of steel blank directly, while small welded pipes and thin-walled welded pipes only need to be welded directly through steel strip.

Alloy pipe seamless steel pipe for high pressure heat resistant alloy pipe and low pressure alloy pipe structure
Alloy pipes are divided into structural seamless pipes and high-pressure heat-resistant alloy pipes. It is mainly different from the production standard and industry of alloy pipe. Annealing and tempering of alloy pipe changes its mechanical properties. Meet the required processing conditions. Its performance is higher than that of ordinary seamless steel pipe, its utilization value is higher, the chemical composition of alloy pipe contains more Cr, and its performance of high temperature resistance, low temperature resistance and corrosion resistance. The common carbon seamless pipe does not contain alloy components or has few alloy components. The reason why alloy pipes are widely used in petroleum, aerospace, chemical industry, electric power, boiler, military industry and other industries is that the mechanical properties of alloy pipes change and are easy to adjust.
