Product details

1.4301 stainless steel bar is a high alloy steel, also known as 304 stainless steel. It contains chromium, nickel, molybdenum, titanium and other alloying elements, with excellent corrosion resistance, high strength, high toughness, good processing properties and welding properties and other characteristics. 1.4301 Stainless steel bar material is widely used in machinery, automotive, petroleum, chemical, pharmaceutical, food, environmental protection and other industries, can be used to manufacture a variety of high-strength, wet-resistant, corrosion-resistant equipment parts and pipeline accessories, such as valves, pumps, pipes, flanges and so on.

Product production process

Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon and other nonmetals to obtain other desired properties. Stainless steel's resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen.

The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products.

The biological cleanability of stainless steel is superior to both aluminium and copper, and comparable to glass. Its cleanability, strength, and corrosion resistance have prompted the use of stainless steel in pharmaceutical and food processing plants.

The density of stainless steel can be somewhere between 7,500kg/m3 to 8,000kg/m3 depending on the alloy.
