Characteristics and scope of application:
SCM440 is commonly used in steel production of high strength fasteners, the product has stable composition, low harmful elements, the purity of steel is high, the advantages of small decarburized layer, surface defects, easy to spheroidizing annealing, low cracking rate of cold heat treatment, stable quality, uniform hardness, widely used in engine, mould etc. industry.
1. good hardenability, deep hardening can be carried out instead of surface quenching in the market
2. the tendency of temper brittleness is less
3.High temperature processing, good appearance after processing
4.Good welding property
5.The impact of the absorption of good performance, hammer hit up with a sense of rebound, can not be violent destruction
We also have a high quality logistics team who We keep more than 10,000 tons SCM440 steel plates in stock each month.we can meet our customer's any quantity request.Based on these stock source,our advantage industry spread into steel process like:cutting (any size and any shape) drilling, welding,milling,machining and steel structure.
We also have a high quality logistics team who make sure the fast delivery time and shipment.
Anyway,if you want SCM440 supplier, please contact us.
