  42CrMo Piston Rod   is manufactured with the highest quality raw materials and the latest machinery, and has passed strict quality inspection. The structure is strong, durable, high tensile strength and mirror surface, which can be widely used in various mechanical equipment. The surface of the 42crmo  chrome-plated piston rod  has been specially ground and treated with a hard chrome plating process. It has a mirror-polished finish and is resistant to friction and corrosion. The piston rod can be used as a guide rod and a pole for various  cylinders , oil cylinders, packaging machines, woodworking machinery, textile machinery, printing and dyeing machinery, die casting machines, injection molding machines and the like. Specifications of 42CrMo Piston Rod 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: A...

  GB 40CR alloy Steel is a high quality Quenched and Tempered Alloy Structural steel, It belong to the high quality low carbon,Low alloy chromium, molybdenum, nickel case hardening steel. Oil Quenched & Tempered Hardness is 28-34 HRc. GB 40CR steel Annealing delivery hardenss less than 250HB. 40CR With a lower carbon content range, So GB 40CR alloy steel have good weldability.

  high tensile 4140 induction hardened chrome bar made from chrome plated steel are typically used in applications where there are heavy duty conditions – often corrosive. The steel contains increased levels of alloying elements which delivers a high grade steel with superior tensile strength exhibiting good machining. 42CrMo4 chrome plated bar is manufactured from low-alloy chromium-molybdenum steel and supported by an induction hardened case offering greater strength and resistance to mechanical damage from external impact. It is used in applications requiring greater yield strength in combination with greater surface impact resistance.
