Detailed Product Description: | 42crmo seamless steel pipe uses: special steel for the bridge as "42crmo", a special steel automobile frames of "42CRmo", a special steel pressure vessel as "42Crmo". Such adjustment is to rely on the carbon steel (C) amount to improve the mechanical properties of the steel, and therefore, according to the level of carbon content, such steels can be divided into: low carbon steel - generally less than 0.25% carbon content, such as 10,20 steel, etc.; carbon steel - carbon content is generally between 0.25 to 0.60%, such as 35, 45 steel, etc.; high carbon - carbon content is generally greater than 0.60%. Such is not generally used in the manufacture of steel pipe. Chemical composition: according to the standard GB / T 3077-1999, the chemical composition of the steel (mass fraction): C0.38% ~ 0.45%, Si0.17% ~ 0.37%, Mn0.50% ~ 0.80%, Cr0.90% ~ 1.20%, Mo0.15% ~ 0.25%, Ni≤0.030%, P≤0.030%, S≤0.030% Physical properties: 1) the critical temperature (approximate): Ac1 = 730C, Ac3 = 800C, Ms = 310C . 2) linear expansion coefficient: temperature 20 ~ 100C / 20 ~ 200C / 20 ~ 300C / 20 ~ 400C / 20 ~ 500C / 20 ~ 600C, linear expansion coefficient: 11.110K / 12.110K / 12.910K / 13.510K / 13.910K14. 110K. 3) elastic modulus: Temperature 20C / 300C / 400C / 500C / 600C, elastic touch 210000MPa / 185000MPa / 175000MPa / 165000MPa / 15500oMPa process specification: Specification heating temperature thermal processing 1150 ~ 1200C, starting temperature 1130 ~ 1180C, termination temperature> 850C , φ> when 50mm, slow cooling. Normalizing specifications normalizing temperature 850 ~ 900C, cooled baked. Tempering specification tempering temperature 680 ~ 700C, cooled baked. Quenching and tempering specification preheating temperature 680 ~ 700C, quenching temperature 840 ~ 880C, oil cooling, tempering temperature 580C, water or oil cooling, hardness ≤217HBW. Hardening process specification quenching temperature 900C, tempering temperature 560C, hardness (371) HRC induction hardening, tempering specification quenching temperature 900C, tempering temperature of 150 ~ 180C, hardness 54 ~ 60HRC.
