40cr Alloy Seamless Steel Pipe
Short Description:
40Cr steel Pipe is a kind of Chinese GB standard alloy steel for engineering and machinery purpose, and one of the most widely used steel grades.
After quenching and tempering treatment, 40Cr steel pipe has good comprehensive mechanical properties, low temperature impact toughness, low notch sensitivity, good hardenability, and high fatigue strength in cold oil. When water cooling, the complicated shape of the parts is prone to cracks, the cold bending plasticity is medium, and the cutting workability after normalizing is good, but the weldability is poor, should be preheated before welding, and is generally used in the state of quenching and tempering.
We’ve been also concentrating on bettering the things management and QC method in order that we could continue to keep terrific benefit inside the fiercely-competitive company for 40cr Alloy Seamless Steel Pipe, We attend seriously to produce and behave with integrity, and because of the favor of consumers in the home and abroad in the xxx industry.
We’ve been also concentrating on bettering the things management and QC method in order that we could continue to keep terrific benefit inside the fiercely-competitive company for 40Cr Alloy Seamless Steel Pipe, The president and all the company members would like to provide specialist solutions and services for customers and sincerely welcome and cooperate with all native and foreign customers for a bright future.
