STKM13C Seamless Steel Tube | JIS G3445 High-Strength Hydraulic Tubing

 JIS G 3445 Grade STKM 13C Seamless Steel Tube, also known as mild steel pipes and tubes.  STKM 13C Tubes are low-cost Low Carbon Steel Tubes with max 025% carbon content that are easy to form and shape. These pipes are manufactured as per JIS Specification and commercially referred to as cds pipes or ms pipes.

STKM13C seamless steel tubes are high-quality carbon steel pipes manufactured under the Japanese Industrial Standard (JIS G3445). Designed for mechanical and structural applications, these tubes combine exceptional strength, dimensional accuracy, and cost-efficiency, making them ideal for:

How To Choose The Cylinder Barrel Materials

Image
  The  cylinder barrel   in which the piston operates must be made of a high-strength material, usually steel. It must be as light as possible, yet have the proper characteristics for operating under high temperatures. It must be made of a good bearing material and have high tensile strength. The cylinder barrel is made of a steel alloy forging with the inner surface hardened to resist wear of the piston and the piston rings which bear against it. This hardening is usually done by exposing the steel to ammonia or cyanide gas while the steel is very hot. The steel soaks up nitrogen from the gas, which forms iron nitrides on the exposed surface. As a result of this process, the metal is said to be nitrided. This nitriding only penetrates into the barrel surface a few thousands of an inch. As the cylinder barrels wear due to use, they can be repaired by chroming. This is a process that plates chromium on the surface of the cylinder barrel and brings it back to new standard d...
