S275 material properties controlled rolling is that, on the basis of adjusting the chemical composition of S275 material properties, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of S275 material properties.
The company will also put Georgetown steelworks on "care and maintenance mode" and temporarily lay off or redeploy about 130 employees working at the steelworks and contractors while some S275 material properties maintenance employees will be on staff during the closure. It is stated that unemployment insurance and state-based unemployment support will be available immediately to workers affected by these changes.
The S275 material properties processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the S275 material properties steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.
