Is 316 Stainless Steel Worth The Extra Cost Over 304?
We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.
There are over 150 grades of stainless-steel, of which fifteen are the most used. 310 Stainless Steel – Austenitic heat resistant grade with larger chromium and nickel for oxidation resistance beyond 2000°F.
To the layman, the differences between one grade of stainless steel and another are easy to overlook. However, to a manufacturer, the distinction between stainless-steel alloys such as grade 304 stainless steel and grade 316 can be big. Excellent weldability by all standard fusion methods, each with and with out filler metals. AS 1554.6 pre-qualifies welding of 316 with Grade 316 and 316L with Grade 316L rods or electrodes (or their excessive silicon equivalents). Heavy welded sections in Grade 316 require submit-weld annealing for maximum corrosion resistance.
Martensitic stainless are usually not appropriate for welding, nonetheless, some martensitic chrome steel grades with decrease quantities of carbon may be welded. With precipitation hardened stainless steels, care should be taken to make sure that the unique mechanical properties aren’t compromised through the welding course of. Grade 316 is the usual molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum provides 316 better total corrosion resistant properties than Grade 304, notably larger resistance to pitting and crevice corrosion in chloride environments.
Our stainless production range
- Stainless steel is normally chosen for its corrosion resistant properties, however you will need to know that different grades provide totally different amounts of corrosion resistance.
- This makes grade 304 an excellent selection when corrosion resistance is essential.
- Austenitic stainless steels usually present the most corrosion resistance because of their high quantities of chromium.
- Grade 316 is just like grade 304, nevertheless it has molybdenum as part of its chemical make-up, additional growing its corrosion resistance.
Grade 316Ti may also be used as an alternative to 316 for heavy section welding. These two alloys are remarkably comparable—but there may be one key distinction. In grade 304 stainless, the maximum carbon content is ready at zero.08%, whereas grade 304L stainless steel has a maximum carbon content of zero.03%. Additionally, the melting point of grade 304 chrome steel is a bit greater than that of grade 316.
If the stainless-steel is going to be subjected to warmth remedy, you will need to know how the assorted grades of stainless-steel may be affected. For essentially the most half, austenitic stainless steels and ferritic stainless steels are non-hardenable when warmth handled.

Grade 316H has larger strength at elevated temperatures and is usually used for structural and stress-containing purposes at temperatures above about 500 °C. Overall, 316 may be worth the expense if you have to have superior corrosion resistance. For many different applications, grade 304 stainless-steel will serve perfectly fine.
But where grade 316 stainless proves superior is its increased corrosion resistance—particularly in opposition to chlorides and chlorinated options. This makes grade 316 stainless significantly fascinating for applications the place exposure to salt or other highly effective corrosives is an issue. Grade 316 is a popular alloy of chrome steel with a melting range of two,500 °F – 2,550 °F (1,371 °C – 1,399 °C). As an austenitic stainless steel alloy, it has qualities such as high energy, corrosion resistance, and high concentrations of chromium and nickel. The alloy has a tensile energy of 579 MPa (84 ksi) and a most use temperature of around 800˚C (1,472˚F).
