ASTM A633 material is particularly suited for service at low ambient temperatures and higher where notch toughness better than that expected in as-rolled material of a comparable strength level is desired. A514 grade B QT steel plate, A633 Grade E high-strength low-alloy structural steel provides a minimum yield point of 60 ksi [415 MPa] in thicknesses up to 4.0 in. [100 mm], inclusive and 55 ksi [380 MPa] in thicknesses over 4 in. to 6 in. [100 to 150 mm], inclusive.
The main problem of safety education in iron and steel enterprises is not that the company does not pay attention to it and does not implement it, but that the subordinate units do not strictly follow the company's requirements. In order to avoid the problem of safety education becoming a mere formality, BBN steel company improved the safety education model from the following aspects: First, the content of safety education should not only pay attention to the accumulation of safety knowledge, but also pay attention to the mastery of safety operation skills.
Hot-rolled coil is a commonly used steel product in the industry. It has a relatively wide variety of products and a wide range of uses. A514 grade B QT steel plate, Hot-rolled coils are widely used in related industries such as petrochemical equipment, automobiles and bridges. Hot-rolled coils are also used in machinery industries such as ships and automobiles because of their good toughness and relatively high strength.
