low alloy hsla plate

АСТМ A572 класс 50 Нержавеющая сталь горячекатаная плита высокая прочность низкая сплавная плита HSLA

A572 Grade 50 steel plate (also known as ASTM A572 Gr. 50, HSLA steel plate, A572-50 structural plate, and high-strength low-alloy steel plate) is a high-strength, low-alloy (HSLA) structural steel plate widely used in construction, bridges, heavy machinery, and transmission towers. Grade 50 offers a minimum yield strength of 50 ksi (345 MPa), providing an excellent strength-to-weight ratio that allows for lighter, more economical structures compared to conventional carbon
