| Material of S45C Hard Chrome Plated Piston Rod : JIS S45C / DIN CK45 / SAE 1045 and JIS S55C. By precision cold drawing, the tensile strength is higher. After harden chrome plating, the chrome shaft obtains good corrosion resistance, great abrasion resistance, uniformity of hardness. Piston Rod can further go through other additional processing like lathing, milling and drilling, etc. Suitable for piston rod, hydraulic cylinder rod, pneumatic cylinder shaft, punching machine, pressing machine, mechanical guide rod, mechanical column bar, solid bar, crane, plastic injection machine, sealing machine, packaging machinery, and other automation machinery. |
| Material of the Europeanization carbon steel chrome plated bar: JIS S50C / DIN CF53 / AISI 1050 and JIS S55C. Through heat treatment, the hardness is greater than common harden chrome plated rod. Induction chrome shaft reaches uniform hardening thickness with no soft spots. It has high stability, low ductility, and superior wear resistance. For mechanical guide rod, tie bar, linear bearing slide rod, excavator, loading machine, construction equipment. |
| Material of Cold Drawn Precision Steel Tube: JIS STKM11A, 12A, 13A to 18C / DIN ST52 / ASTM A106. Cold Drawn Precision Steel Tube within precise interior diameter has great surface roughness, better than hot rolled tube. Specifications can be customized to achieve higher degree of tensile strength, yield strength, elongation. Cold Drawn Precision Steel Tube is suitable for gas cylinder, hydraulic cylinder, shock absorber of automobile, motorcycle and bicycle use. Besides, Cold Drawn tube can also be used in air-conditioning condenser, front fork and rear fork of motorcycle, mechanical arm and exhaust pipe. |
| 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. 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 pipe, bulldozer, forklift, construction machinery, dump truck, and vertical parking system. |
| Seamless Stainless Steel Honed Pipe Materials: SUS304. SUS304 has below features: nice corrosion resistance, good abrasion resistance, low magnetism and long working life. Seamless Stainless Steel Honed Pipe can be applied to office furniture, food machinery, packaging machinery, pneumatic and hydraulic equipment, car washing equipment, medical equipment and other advanced precision equipment. Seamless Stainless Steel Honed Pipe is available for OEM service. |
| Commonly known as “Red Cross”. Alloy Chromium Plated Steel Bar is made of JIS SCM440 / DIN 42CrMo4 / AISI 4140. Cr-Mo Alloy Chromium Plated Steel Bar has greater tensile strength, yield strength, and elongation than medium-carbon hard chrome shaft. Thermoechanical treatment can be added. Through heat treatment, induction, the bar achieves high degree of scalability. Applies to piston rod, hydraulic cylinder bar, pneumatic cylinder rod, mechanical guide bar, all kinds of machinery column rod, sport equipment, aerospace engineering, and various types of machinery. |
