Is 304 or 316 stainless steel better?
A ferritic stainless steel owes its magnetism to two factors: its high concentration of iron and its fundamental structure. Both 304 and 316 stainless steels are austenitic, when they cool, the iron remains in the form of austenite (gamma iron), a phase of iron which is nonmagnetic.
Stainless Steel
Low carbon content means less carbide precipitation within the heat-affected zone during welding and a decrease susceptibility to intergranular corrosion. To the layman, the differences between one grade of stainless steel and another are easy to miss. However, to a producer, the distinction between chrome steel alloys corresponding to grade 304 chrome steel and grade 316 can be large. Stainless 316 is dearer as a result of it supplies the next corrosion resistance, especially against chlorides and chlorinated solutions. This makes stainless 316 more fascinating in purposes the place salt publicity is a matter.
It can be potential for austenite to spontaneously convert to martensite at low temperatures. To complicate issues additional, the magnetic properties of these alloys rely upon the alloy composition.
Grade 316 has particularly better resistance to salt and chloride pitting. Pitting corrosion can occur when chrome steel alloys, similar to grade 304 stainless steel, come into contact with salt-rich sea breezes and seawater.
- This makes grade 316 stainless notably fascinating for purposes where exposure to salt or different highly effective corrosives is a matter.
- But where grade 316 stainless proves superior is its elevated corrosion resistance—significantly in opposition to chlorides and chlorinated options.
- Though the stainless steel 304 alloy has a better melting level, grade 316 has a better resistance to chemical compounds and chlorides (like salt) than grade 304 stainless steel.
- The elevated nickel content and the inclusion of molybdenum makes grade 316 stainless steel a bit costlier than grade 304 per ounce of material.

However, the closer grade 304 stainless steel reaches its melting level, the extra tensile strength it loses. Besides the rough environment of the ocean and marine purposes, chlorides, corresponding to salt, can eat away at even the toughest metals. Salt will even compromise the protective oxide layer of grade 304 chrome steel, resulting in rust. For marine functions, or processes involving chlorides, grade 316 stainless-steel is ideal.
The main difference between 304 vs 316 stainless-steel is the composition and corrosion resistance, SS304 doesn’t contain molybdenum while SS316 accommodates 2-three% molybdenum. The addition of molybdenum offers pitting resistance in phosphoric acid, acetic acid and dilute chloride solutions and provides corrosion resistance in sulfurous acid. In addition,AISI 304 has a 18% Cr and 8% Ni and therefore known as 18-8 stainless-steel, whereas AISI 316 has a 16% Chromium and 10% Nickel. If you’ve an utility with very highly effective corrosives or relies on chlorides, then paying a premium for grade 316 stainless steel is definitely price it. In such purposes, 316 stainless will last many instances longer than grade 304 chrome steel would—which may imply many further years of helpful life.
The austenitic stainless steels are also considered to be the most weldable of the high-alloy steels and could be welded by all fusion and resistance welding processes. High ductility, excellent drawing, forming, and spinning properties. Essentially non-magnetic, turns into barely magnetic when chilly worked.

When stronger corrosion resistance is needed, different alloys, similar to grade 316 stainless steel, are normally thought-about instead. Another well-liked high-performing alloy, grade 304 chrome steel is a sturdy materials by way of tensile power, 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).
