PRODUCT DESCRIPTION
30ХГСH2А 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 bright in the annealed condition, or bright annealing specially.
Final heat treatment: quenched and tempered.
Rod, round bar, disc (diameter): 6.0 ~ 800 mm
Square bar, flat bar (width) : 10 ~ 600 mm
Plate, sheet via cold & hot rolled / forged: THK 0.3 ~ 300 X wide 10 ~ 1000 X L mm
TECHNICAL SALES ASSISTANCE & SERVICE
Stock over 60 grades with a competitive price, along with cutting service for specific requirement.
Customizing special material is welcome.
