Stainless steel is a material that you often encounter in everyday life. You often find it on cooking utensils. Interestingly, stainless steel is still popular because it is more durable, easy to clean, and food-grade. In addition to its advantages, stainless steel itself consists of various types.
What Is Stainless Steel?
Before discussing the differences between 316 stainless steel and 304 stainless steel, you must know what stainless steel is. You know that every steel has the same basic iron and carbon composition. However, stainless steel also contains chrome composition, as an alloy that can provide corrosion resistance which is well known to the stainless steel material.
SS 304 fasteners manufacturers in India provides several grades of stainless steel, each with a different alloy composition. Therefore the physical characteristics are slightly different.
But you must know that stainless steel must contain at least 10.5% chromium. Usually, depending on the grade may have much higher levels of chromium and other additional guide ingredients? You can Call it molybdenum, titanium, nickel, copper, aluminium, selenium, phosphorus, or nitrogen.
Chromium in stainless steel helps the process of binding oxygen to the surface of the stainless steel material to protect the iron against the oxidation process, which causes rust. The high chromium content can certainly affect the resistance of stainless steel to rust or corrosion. Super Duplex Pipe suppliers in India offers the best products at a wide range. While the composition of the other contents is different in nickel, chromium, iron, carbon, or others, making the SS code different.
- Stainless Steel 304
Stainless steel 304 is the most commonly used form of stainless steel worldwide due to its excellent qualities and resistance to corrosion. 304 stainless steel contains at least 16-24% chromium and 35% nickel, and small amounts of manganese and carbon.
SS 304 can resist corrosion to most oxidizing acids. This tool is also useful for decorating, building, and furnishing. SS 304 has one weakness: being susceptible to corrosion by chloride solutions or from the coastal environment. Chloride ions can create localized areas of corrosion known as pitting. Then it can spread on the underside of the chromium shield to contaminate the internal structure.
- Stainless Steel 316
Stainless steel 316 is the second most commonly used form of stainless steel. SS 316 has almost the same mechanical and physical properties as SS 304 and contains similar make-up ingredients. The difference is stainless steel 316 contains about 2-3% molybdenum. The addition of this content can improve corrosion resistance, especially to chlorides and other industrial solvents.
SS 316 has added molybdenum, which resists chlorides and other processing chemicals. Usually, stainless steel 316 is applied in various industrial applications involving chemicals and environments with high salinity, such as coastal areas. 300 series grades contain up to 7% molybdenum. SS 316 fasteners manufacturers in India provides better chloride resistance material, but this resistance is only required in high concentrations.
Common uses of SS 316 include pharmaceutical manufacturing, chemical manufacturing, chemical, and industrial transportation, pressure vessels, tanks and piping for chemical applications, non-surgical steel medical equipment, marine equipment, commercial equipment, and production processes.
