What kind of Stainless Steel is not easy to rust

Issuing time:2020-09-04 09:48Author:Allen

There are three main factors affectingstainless steel corrosion:

1) The content of alloying elements,generally speaking, the content of chromium in 10.5% steel will not rusteasily.

Chromium nickel:The higher the content, the better thecorrosion resistance. For example, the content of nickel for 304 material is 8-10%, and the content of chromium reaches 18-20%. Such stainless steel willnot rust under normal circumstances.

2) Thesmelting process of the manufacturer will also affect the corrosion resistanceof stainless steel. A large stainless steel plant with good smeltingtechnology, advanced equipment and advanced technology can guarantee thecontrol of alloying elements, the removal of impurities, and the control of thecooling temperature of the billet, so the product quality is stable andreliable, the internal quality is good, and it is not easy to rust. On thecontrary, some small steel mills have backward equipment and technology. Duringthe smelting process, impurities cannot be removed, and the products producedwill inevitably rust.

3) Externalenvironment, dry and ventilated environment is not easy to rust. However, theair humidity is high, continuous rainy weather, or the environment with high pHin the air is easy to rust. 304 stainless steel, if the surrounding environmentis too bad, it will rust.

Investment Casting also to be called Precision Casting, lost wax casting, the material   including Stainless Steel, various alloy steel, carbonsteel, etc.

As a professional Precision Casting Manufacturer, we also have strong Machining strength, with all kinds of Japanese imported and domestic processing equipment, to ensure that the product machining requirements are qualified.
