PRODUCT DESCRIPTION
20ХГHTP is usually produced by EAF + LF + VD / EF 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 bright in the annealed condition, or bright annealing specially.
Final heat treatment: quenched and tempered.
Rod, round bar, disc (diameter): 6.0 ~ 820 mm
Square bar, flat bar (width) : 10 ~ 550 mm
Plate, sheet via cold & hot rolled / forged: THK 0.5 ~ 320 X wide 20 ~ 800 X L mm
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.
Steel bar and steel forgings for barrel of middle-small caliber quick firing arms.
Power generation, turbine fasteners, boiler support rods.
Process plant, fasteners, Mechanical gears, gear shaft, main axis, valve rod.
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.
