TYPICAL APPLICATIONS
Alloy structural steels are widely used in the filed of ship, vehicle, airplane, guided missile, weapons, railway, bridges, pressure vessel, machine tools, mechanical components with a bigger sectional size and so on.
Mechanical parts - connecting rod, bolt and nuts.
Multi-diameter shaft, pressure vessel parts.
Power generation – turbine fasteners – boiler support rods.
Process plant – fasteners, mechanical gears, gear shaft, main axis, valve rod.
PRODUCT DESCRIPTION
12Cr2Mo1 is usually produced by EAF + VD + LF / BEF followed by electroslag refining (ESR) if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bars are usually supplied black in the annealed condition.
Final heat treatment - normalized + tempered.
TECHNICAL SALES ASSISTANCE & SERVICE
20+ years focus on special steel manufacturing and processing.
Stock over 60 grades with a competitive price, along with cutting service for specific requirement.
Customizing special material is welcome.
We closely cooperate with the professional inspection partners to strictly control the quality and improve the quality manage system, and guarantee the goods delivery each time. It is proved that we are worth of trusting and will be the strategic partner of the supplying chains in the special steels field.
