FAQ
Q: What grade of steel is SS540?
A: SS540 material is a structural hot rolled steel grade defined under JIS G 3101. It is distinguished by its superior tensile strength, with a minimum of 540 N/mm2 (MPa). The material has a thickness range of 6 mm to 120 mm and offers robust mechanical properties.
Q: What is the difference between SS400 and SS540?
A: Compared with SS400 & SS490, SS540 has much higher strength - 400 MPa yield strength and 540 MPa tensile strength. High strength makes it popular for applications where need strength but weight is an issue.
Q: What is the steel equivalent of SS540?
A: SS 540 steel plate's equivalent grade is DIN 17102 STE 380, NFA 36201 E 375R, MNC 810E SS21,42,01, CSA G40-21 400 W, WT, ASTM A 572 gr. 60 & 65.
