How can I tell if my stainless steel is 304 or 316?
Though the stainless steel 304 alloy has a higher melting point, grade 316 has a better resistance to chemicals and chlorides (like salt) than grade 304 stainless steel. When it comes to applications with chlorinated solutions or exposure to salt, grade 316 stainless steel is considered superior.
This reduces pitting from chemical environments and allows grade 316 chrome steel to be used in extremely acidic and caustic environments that might otherwise eat away on the metallic. For instance, grade 316 stainless steel can face up to caustic solutions and corrosive applications corresponding to vapor degreasing or many other components cleaning processes. The minimum 10.5% chromium in stainless steels supplies resistance to roughly 700 °C (1,300 °F), while 16% chromium offers resistance up to approximately 1,200 °C (2,200 °F). Type 304, the most typical grade of stainless-steel with 18% chromium, is immune to roughly 870 °C (1,600 °F). Other gases, similar to sulfur dioxide, hydrogen sulfide, carbon monoxide, chlorine, also assault stainless-steel.
The molybdenum offers 316 higher general corrosion resistant properties than Grade 304, significantly greater resistance to pitting and crevice corrosion in chloride environments. It is quickly brake or roll fashioned into a variety of parts for purposes within the industrial, architectural, and transportation fields.
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.
- Stainless steels have an extended history of utility in touch with water due to their excellent corrosion resistance.
- Types 304 and 316 stainless steels are standard supplies of building involved with water.
- Other austenitic stainless steels, such as grade 304 SS, can experience extreme pitting corrosion when uncovered to salt, which is commonly present in food products.
- What makes the grade 316 alloy an ideal meals grade steel sheet materials is the fact that it has a excessive resistance to acids, alkalis, and chlorides .
The most basic difference between grade 304 and grade 316 stainless steels is that 316 tends to have extra nickel and a little bit of molybdenum in the mix. The common mechanical properties of the two metals are mostly comparable.
Increasing chromium and nickel contents present elevated resistance. The elevated nickel content material and the inclusion of molybdenum makes grade 316 chrome steel a bit costlier than grade 304 per ounce of material. 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 notably desirable for applications where publicity to salt or other highly effective corrosives is an issue. Grade 316 is a popular alloy of stainless steel with a melting range of two,500 °F – 2,550 °F (1,371 °C – 1,399 °C).
What makes the grade 316 alloy an ideal meals grade steel sheet material is the truth that it has a high resistance to acids, alkalis, and chlorides . Other austenitic stainless steels, such as grade 304 SS, can expertise severe pitting corrosion when exposed to salt, which is usually present in meals products. Stainless steels have a long historical past of utility in touch with water due to their excellent corrosion resistance. Applications embrace a variety of conditions including plumbing, potable water and wastewater remedy, desalination, and brine therapy.
astm a269 tp316l
As an alloy, stainless-steel 430 food grade steel is similar to grade 316 stainless. It has the same chromium content material as 316, however only a fraction of the nickel content, which makes it a extra reasonably priced different for some food makers. Grade 316 stainless is an austenitic stainless-steel alloy with a high chromium and nickel content.

What is ASTM a240?
ASTM A240 specification covers stainless steel plates, sheets and strips for pressure vessels and general applications. This specification covers chemical composition and mechanical properties for various grades of ferritic, austenitic, martensitic, duplex, super duplex and high moly stainless steel alloys.
Another in style high-performing alloy, grade 304 chrome steel is a durable material when it comes to tensile strength, sturdiness, corrosion, and oxidation resistance. The melting point of stainless steel 304 is reached at temperatures ranging between 2,550 °F – 2,650 °F (1399 °C – 1454 °C). However, the closer grade 304 stainless-steel reaches its melting level, the more tensile strength it loses. Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels.
