Effect of main elements in stainless steel

As compared with stainless steel special steel products added value, more and more widely used, both in civilian areas such as decoration, kitchenware, household appliances; or industrial fields such as petroleum chemical industry, machinery and equipment are widely used at present, the high quality stainless steel products market is still optimistic about the prospects. Below, let us work together to understand the production of stainless steel required for the main elements of the relevant functions:

Nickel: nickel stainless steel is the most important core elements, which can improve the strength and toughness of steel, improve hardenability. High content, can significantly change the physical properties of steel and alloy, improve the corrosion resistance of steel.

Manganese can improve the strength of steel, can weaken and eliminate the adverse effects of sulfur, and can improve the hardenability of steel, manganese content of high alloy steel (Gao Menggang) has good abrasion resistance and other physical properties.

Chromium: can improve the hardenability and wear resistance of steel, can improve the corrosion resistance and anti-oxidation of steel.

Vanadium: can refine the grain structure of steel, improve the strength, toughness and wear resistance of steel. When it is melted into austenite at high temperature, the hardenability of the steel can be increased; on the contrary, when it exists in the carbide form, it will reduce its hardenability.

Mo: can obviously improve the hardenability of steel and heat resistance, prevent tempering brittleness, higher remanence and coercive force.

Titanium: steel grain structure can be refined, thereby enhancing the strength and toughness of steel. In stainless steel, titanium can eliminate or mitigate the intergranular corrosion of steel.

Copper: its prominent role is to improve the atmospheric corrosion resistance of ordinary low alloy steel, which is more obvious when combined with phosphorus.
