After adding phosphorus, copper, chromium, nickel and other trace elements to the steel, a dense and highly adherent protective film is formed on the surface of the steel, which hinders the spread and development of rust and protects the substrate under the rust layer to slow down its corrosion rate. The amorphous spinel-type oxide layer with a thickness of about 50μm-100μm formed between the rust layer and the substrate is dense and has good adhesion to the substrate metal.
The SPA-H rusty steel for sculpture 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 SPA-H rusty steel for sculpture 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.
We have a large number of SPA-H rusty steel for sculpture steel materials in stock, and provide deep processing services such as welding. In addition to simple welding parts, we can also weld H-beam, box column and other profiles. For such welded structure, our advantage is that there are high-quality and low-cost raw material steel plates, which can be cut into the SPA-H rusty steel for sculpture required size and welded into steel products with required shape and size, without being limited by the specifications of rolling production lines.
On October 16, 2019, the Board of Directors of the World Steel Association (worldsteel) elected the following new officers for 2019/2020 at the worldsteel General Assembly in Monterrey. The new SPA-H rusty steel for sculpture officers are elected for a one-year period: Chairman - YU Yong, Chairman, HBIS Group Co., Ltd. Vice Chairman - Sajjan JINDAL, Chairman and Managing Director, JSW Steel Limited.
