Introduction:
Product Name: JIS G3445 Welded Precision Cold Drawn Carbon Steel Tube
Product Description: The material used in The JIS G3445 Welded Precision Cold Drawn Carbon Steel Tube is a carbon steel, which has good mechanical properties and machinability. It is generally suitable for the requirements of welded precision cold-drawn carbon steel pipes in mechanical structures, automobiles, motorcycles, bicycles and other industries, and they are usually used in occasions with high dimensional accuracy and surface quality.
Material:
Grade: STKM11A, STKM12A, STKM13A, STKM14A, STKM15A, STKM16A, STKM17A, STKM18A, STKM19A, STKM20A, STKM25A, STKM27A, STKM29A, STKM30A, STKM34A, STKM35A, STKM38A, STKM39A, STKM40A, STKM41A, STKM42A, STKM45A, STKM46A, STKM47A, STKM48A, STKM49A, STKM50A
Chemical Composition: The steel tube is made from high-quality carbon steel, which typically includes elements such as carbon, manganese, phosphorus, sulfur, and silicon. This composition provides excellent mechanical properties, including high strength, ductility, and weldability.
Features:
High dimensional accuracy:
These tubes are precision cold drawn and therefore have high dimensional accuracy, including outer diameter, inner diameter and wall thickness.
The dimensional tolerances are tightly controlled, which can meet the requirements of precise fit.
Good surface finish:
The cold drawing process can make the surface of the steel pipe smoother, reduce surface defects, and meet the requirements of high surface quality.
Stable mechanical properties:
The steel pipe material is carbon steel, and the welding and cold drawing process ensures that the steel pipe has good mechanical properties, such as tensile strength, yield strength and elongation.
Strict control of chemical composition:
The standard has clear regulations on the chemical composition of steel pipes, including the content of carbon, manganese, silicon, sulfur, phosphorus and other elements, which ensures the uniformity and stability of the material.
Reliable welding quality:
The welded part of the steel pipe undergoes strict quality control to ensure that the weld is firm and free of gaps and cracks.
Corrosion Resistance:
Depending on the need, the steel pipe can be surface treated, such as galvanized, copper, etc., to improve its corrosion resistance.
Wide range of applicability:
Due to their excellent properties, these steel pipes are suitable for a variety of industrial fields, including automobiles, motorcycles, bicycles, mechanical structures, and more.
Strict inspection and testing:
Steel pipes need to go through a series of inspections and tests before production and delivery, including chemical composition analysis, mechanical property testing, dimensional measurement and non-destructive testing.
Technical Specifications:
Outer Diameter: Customizable (commonly ranging from 6mm to 350mm)
Wall Thickness: Customizable (commonly ranging from 0.8mm to 35mm)
Length: Customizable
Tolerance: According to JIS G3445 standard or customer requirements
Surface Finish: Smooth surface finish achieved through the cold drawing process
Mechanical Properties:
Tensile Strength: Varies depending on the specific grade and material used
Yield Strength: Varies depending on the specific grade and material used
Elongation: Varies depending on the specific grade and material used
Hardness: Varies depending on the specific heat treatment and application requirements
Chemical Composition (Percentage):
