S355JR High-strength Steel Plate
S355JR Low-aloy (HSLA) Steel Products Description
S355JR alloy steel plate is a low alloy high strength structural steel that can maintain its shape and performance when subjected to shock or vibration, and has high tensile strength and yield ratio.
S355JR high tensile steel plate is easy to carry out various welding processes, such as manual arc welding, submerged arc welding, etc. S355JR hsla structural steel has good cold processing properties and hot processing properties, and is easy to cut, bend and form.
S355JR high tensile alloy steel engineering application areas:
Construction field: used for beams, columns, floor slabs and other parts of building structures such as high-rise buildings, factories, bridges, etc.
Ship field: used for the production of structural components such as decks, bulkheads, trusses, etc. of ships.
Machinery field: used to manufacture structural parts of various heavy machinery and equipment.
