42CrMo Chrome Bar Hard Plated Piston Bar Cold Drawn Steel Bar Precision Cylinder Bar Hollow Steel Bar

42CrMo Chrome Bar Hard Plated Piston Bar Cold Drawn Steel Bar Precision Cylinder Bar Hollow Steel Bar

42CrMo hard chrome plated steel bars are chromium-plated steel products that can be supplied as piston rods in standard hydraulic and pneumatic applications. The hard chrome plated steel bar is normally used in conditions of high stress, friction and harsh climactic environments

Product Details

1.Brief Introduction to 42CrMo Chrome Plated Steel Bar

Chrome plated steel bars are chromium-plated steel products that can be supplied as piston rods in standard hydraulic and pneumatic applications. The chrome plated steel bar is normally used in conditions of high stress, friction and harsh climactic environments, so the quality of the base metal and subsequent surface treatment are of paramount importance. Wear resistance, corrosion resistance, surface smoothness, high yield strength and uniform quality are essential properties of hard chrome bar.

Hard Chrome bars are generally produced from steel bars combining high strength with excellent machinability and weldability. Common applications are found in agricultural machinery, production equipment, cranes, garbage compactors, lifters etc.

2.Steel Grade according to different standards

China steel grades: GB standard

42CrMo

Germany steel grades: DIN standard

42CrMo4

Japanese steel grades: JIS standard

SCM440

American steel grades: AISI Standard

4140

4.Work Flow

Hardening
High-frequency induction hardening guarantees the surface hardness and optimum strength of the material, which makes the shaft highly durable and resistant to abrasion. We can supply several conditions as follows:
1.Hard chrome plated (surface without heat treatment)
2.High-frequency induction hardened hard chrome plated
3.Quenched and Tempered
4.Induction hardened with Q&T
Centerless Grinding
Our grinding lines work at high processing speeds with optimum efficiency. Depending on material and diameter requirements, surface qualities with roughness specifications up to Ra0.2μm can be obtained.
Surface Treatment
By hard chrome plating, your components obtain a high resistance to corrosion and wear. This means high endurance over the entire life of the product. Usually, the thickness of hard chrome plating is 10μm~5μm. Resistance in front salt spray (fog) test environment according to the ASTM B-117-97 could be 36 hours.
Polishing
We can guarantee you mirror-like polished surfaces with our optimal finish grinding method without material loss.

5.Why Choose Us?

1.Raw material of piston rod is mainly from the best and largest raw material manufacturers in China, such as TPCO, BAO STEEL, SHA STEEL etc.

2.Plate on piston rod is according to customers’ different requirements, such as Chrome, Nickel, and Ceramic.
