Interior Honed with Exterior Hard Chromium Plated Tube (Hollow Shaft)


Interior Honed with Exterior Hard Chromium Plated Tube (Hollow Shaft)

Material of seamless pipe: JIS STKM 13C/ DIN ST 52/ ASTM A106/ SAE 1020 and welded tube: DIN ST 52.3 are provided. ST52 and ST52.3 tubes with good weldability and high yield strength withstand higher pressure, and have good impact resistance in low temperature. JIS STKM 13C/ SAE 1020 also aim at mechanical structual use with similar but less working pressure than ST52. Suitable for lathing and other further processing. Tube with ID honed and OD hard chrome plated is oxidization resistance, and has high working efficiency because of great ability of oil storage. Energy saving, long working life. Applies to telescopic cylinder tube, bulldozer, forklift, construction machinery, dump truck, tipping system and vertical parking system.
