40cr pipe; [specification] quenching quenching temperature 850 ℃ ± 10 ℃, oil cooling; tempering temperature of 520 ℃ ± 10 ℃, water, oil and air cooling. [Features] carbon steel alloy tube modulation, cold heading die steel. The steel affordable, easy processing, the availability of appropriate heat treatment after a certain toughness, ductility and wear resistance. Normalizing can promote tissue ball 12gr1mov alloy tube, improved cutting hardness of less than 160HBS blank. Tempered at a temperature of 550 ~ 570 ℃, the steel has the best mechanical properties. The steel hardenability than 45 steel, suitable for high-frequency hardening, flame hardening and other surface hardening treatment. [Applications] This post-quenched steel used in manufacturing under moderate loads and moderate speeds of mechanical parts, such as automotive knuckles, and rear axle gears, shafts, worm, spline shaft, sets and other tools on top ; after quenching and tempering for the manufacture of high loads, impact and medium speed parts work 35crmo alloy tube, such as gears, spindles, oil pump rotor, sliders, rings, etc; after quenching and tempering for manufacturing heavy duty, low impact and abrasion resistant, the cross-sectional thickness of 25mm or less part of the entity, such as a worm, spindles, shafts, rings, etc; quenched and later used in the manufacture of high-frequency surface hardening has a high surface hardness and abrasion resistance without a great impact on the parts such as gears, the sleeve, shaft, shaft, crankshaft, spindles, pins, connecting rods, screws, nuts, intake valves and the like. In addition 10crmo910 alloy tube, steel and suitable for the manufacture of such conduct carbonitriding process various transmission parts, such as large diameter and low temperature toughness, good gear and shaft. 12cr1mov difference with 15crmo steel pipe Published: 2015-5-3 good cold working properties and weldability, below 520 ℃, with high rupture strength and good oxidation resistance. Applications: steam pipe wall temperature ≤510 ℃, the header; the wall temperature of the heating surface tubes ≤540 ℃.
