40CrV alloy structural steel round bar Tolerance

40CrV, alloy structural steel. Unified digital code: A23402. 40CrV alloy structural steel round bar,having high strength and high yield, better mechanical performance than the 40Cr. Cold plastic deformation resistance are in the intermediate and cutting, thermal sensitivity is small, but there is a tendency to temper brittleness and white spots sensitivity. Usually in the quenched state use.

40CrV alloy structural steel bar for the manufacture of variable load, high load various important parts, such as motorcycle connecting rod, bushings, brackets, studs, screws, not carburized gears, the nitriding treatment various gears and the pin, high-pressure boiler water pump shaft (diameter less than 30mm), high-pressure cylinder and the like.
