Jis G3539 Pdf

The performance of JIS G3539 steel depends heavily on tight control over alloying elements. Impurities like phosphorus and sulfur are strictly minimized to prevent internal tearing during cold forming. Carbon (C) % Silicon (Si) % Manganese (Mn) % Phosphorus (P) max % Sulfur (S) max % 0.08 – 0.13 0.30 – 0.60 SWCH35K 0.32 – 0.38 0.10 – 0.35 0.60 – 0.90 SWCH45K 0.42 – 0.48 0.10 – 0.35 0.60 – 0.90 4. Mechanical Properties and Microstructure

The JIS G3539 standard applies to steel wires with diameters ranging from 0.1 mm to 30 mm, used in various fields such as:

Ensuring incoming raw materials exactly match Japanese manufacturing blueprints.

The surface must be free from harmful scale, rust, or defects that could interfere with the cold heading or forging process. Typical Grades and Properties jis g3539 pdf
