The great advantages of stainless steel 316 that you need to know
Stainless steel 316 coil is one of the most popular products in the industry. What is the advantage of stainless steel 316? Let’s find us.
Stainless steel 316
Stainless steel 316 is the standard molybdenum stainless steel. It is second most common in stainless steel after 304 stainless steel among Austenitic stainless steels. Molybdenum makes 316 better overall corrosion resistance, 304 better abrasion resistance. Especially high resistance to pitting and corrosion erosion in chloride environment. The welding ability of the 316 / 316L stainless steel is excellent. It’s easy machining to form a variety of parts for applications. In the fields of architecture, transportation and industry. Inox 316 has excellent welding ability so no need for heat treatment before and after welding.
Stainless steel 316L
Inox 316L, the low carbon version of the 316 is better than the 316 stainless steel. So it is widely used in heavy, heavy components (usually over 6mm). Stainless steel 316H, with higher carbon content for applications at high temperatures, or at high temperatures we can also use stainless steel 316Ti.
The austenitic structure also gives these types of excellent toughness, even down to minus temperature.
Important properties of stainless steel 316
These properties are indicated for flat rolled products (sheets, coils and welded tubes) in ASTM A240 / A240M. Similarities, but not necessarily identical. Which is specified for other products such as pipes and round bars (Stainless Steel Inox 316) in the corresponding specifications.
Corrosion resistance of stainless steel 316
Corrosion resistance of Inox 316 is excellent in air and highly corrosive solutions. At a temperature of 60 ° C and in a chloride environment, cracks are more likely to corrode than about 1000 mg / L of chloride at ambient temperature, down to about 500 mg / L at temperatures below 60 ° C.
Stainless steel 316 is often referred to as the “Offshore Materials” standard. But it does not have the ability to resist warm water as mentioned above. In many environments, stainless steel 316 can often be seen dyed brown. This is particularly prominent at cracking and rugged surfaces.
Heat resistance of stainless steel 316
Good oxidation at discrete temperatures is 870 ° C and continuous 925 ° C. Using stainless steel 316 safely at temperatures from 425 to 860 ° C in dry heat is not recommended for use in heat-resistant media. such height. Stainless steel 316L is also recommended for use in the upper heat range. Class 316H is more durable at higher temperatures and is sometimes used for structural applications and pressures above 500 ° C.
Heat treatment
If you want to work in high temperatures, heat inox 316 between 1010-1120 ° C processing and fast cooling to keep the mechanical properties. Stainless steel 316 can not be hardened by heat treatment.
Welding capacity of stainless steel 316
Stainless steel 316 is excellent for all types. Welding methods, heavy welds (heavy industry) should be annealed after welding. To maintain maximum corrosion resistance at welding lines. The 316Ti stainless steel can also be used as a replacement for the 316 to meet the application needs.
Machining capacity of stainless steel 316
Stainless steel 316 is not specialized for precision machining. However, some applications need to use stainless steel 316 so the 316 stainless steel manufacturers designed a special version for Inox 316 stainless steel 316 Ugima. This is better than the standard 316 or 316L, due to higher processing costs.
