35CrMo is an alloy structural steel with high static strength, impact toughness and high fatigue limit.
35CrMo steel material belongs to alloy structural steel. 35 refers to the carbon content of about 35%, Cr is chromium, and Mo is molybdenum.
35CrMo steel material has high static strength, high impact toughness, high fatigue limit, higher hardenability than 40Cr steel, high temperature resistance, long-term working temperature can reach 500 ℃, poor welding performance.
The main applications of 35CrMo steel material are: it can be processed into important structural parts working under high load, such as the transmission parts of vehicles and engines; the rotor, main shaft, transmission shaft of heavy load and large section parts of turbogenerator.

Characteristic:35CrMo has high static strength, impact toughness and high fatigue limit, harden ability is higher than 40Cr , higher creep strength and lasting strength under high temperature , long-term working temperature up to 500 ℃.
Application: 35CrMo alloy pipe is used to manufacture important parts of various machines that bear the impact, twist and high
Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
