What is the wheel of a crane
There are two kinds of materials, one is cast steel and one is forgings. Castings are usually zg340-640 cast steel or zg-50simn low alloy steel, which is generally 65mn, and occasionally USES 42CrMo!
Common materials for crane wheel forgings: 60 steel is the most commonly used price 65Mn is also commonly used 42CrMo price point, good quality! Then there is the 50SiMn 55 steel shanxi yongxin professional forging crane wheel of his whole point!
Wheel the ZG340-640 cast steel or mid-december to 50 simn low alloy steel, face need quenching, depth of not less than 20 mm. For ZG340-640 cast steel wheel, rolling surface hardness is 300-350 HBW, in mid-december, and 50 simn, rolling surface hardness is 420-480 HBW.
