JIS SM570 steel is a kind of welding structural steel in the standard JIS G3106. SM570 steel offers proper yield and tensile strength and is supplied with a variety of treatments. It is usually supplied in control rolled delivery condition.
JIS SM570 steel yield strength:
| Grade | Yield strength MPa | Tensile strength MPa | Elongation | |||
| SM570 | t≤16 | ≥460 | t≤100 | 570-720 | - | |
| 16<t≤40 | ≥450 | t≤16 | ≥19 | |||
| 40<t≤75 | ≥430 | 100<t≤200 | - | 16<t | ≥26 | |
| 75<t≤100 | ≥420 | t>40 | ≥20 | |||
| 100<t≤200 | - | - | - | |||
JIS SM570 steel shares good fatigue resistance, high toughness, good cold forming performance and welding performance. JIS SM570 steel has a certain degree of corrosion and wear resistance. It is commonly used in the engineering and construction industry.
