Note: The "R" suffix typically denotes rimmed steel, while "A" indicates aluminum-killed steel. 3. Mechanical and Physical Properties
For a look at chemical compositions and forging properties of SWCH 10A , check these additional Scribd technical specs. Material - JIS G 3539 SWCH 8R - Gravity Group of Companies
Many engineers confuse JIS G3539 with similar standards. Here’s a quick comparison:
JIS G 3539 specifies the requirements for carbon steel and alloy steel wire rods intended for cold heading and cold forging. Unlike generic steel standards which may focus solely on tensile strength or chemical composition, G 3539 places a heavy emphasis on . jis g3539 pdf

Carbon Content | Typical Applications | Global Equivalent (Approx.) | |:---|:---|:---|:---| | SWCH8A | ~0.08% | Low-strength rivets, small screws | C8C, AISI 1008 | | SWCH12A | 0.10-0.15% | Standard bolts and nuts | CC11A, C10C | | SWCH22A | 0.18-0.23% | Machine screws, high-strength bolts | C22C, AISI 1022 | | SWCH35K | ~0.35% | High-strength bolts, automotive parts | C35C, AISI 1035 | | SWCH45K | ~0.45% | High-hardness parts | C45C, AISI 1045 |
What (e.g., bolts, rivets) you are manufacturing?
Often used for components requiring specific heat treatment or annealing. Note: The "R" suffix typically denotes rimmed steel,
The wire manufactured under JIS G 3539 is indispensable in several industries:
Utilizing the exact testing methodologies prescribed by the Japanese Standards Association (JSA).
