Metals That Don’t Rust
black stainless steel sheet
Please seek the advice of current editions of requirements for design properties. Austral Wright Metals assumes no liability in reference to the information on this Product Data Sheet. Austral Wright Metals provides a complete vary of stainless steels, copper alloys, nickel alloys and different excessive performance metals for challenging service conditions. Our engineers and metallurgists shall be happy to supply additional information and applications advice. The very robust and ductile austenitic structure provides grade 316 excellent formability and fabrication characteristics.
More just lately, the cheaper (and barely much less corrosion-resistant) lean duplex has been developed, chiefly for structural applications in building and building and within the water trade. Ferritic stainless steels possess a ferrite microstructure like carbon steel, which is a body-centered cubic crystal structure, and include between 10.5% and 27% chromium with very little or no nickel.
We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.
Characteristics of Stainless Steel Sheet and Plate:
High corrosion resistance
High toughness and impact resistance
High workability, including machining, stamping, fabricating and welding
Smooth surface finish that can be easily clean
Through it is very important observe that some grades are more immune to rust than others. Austenitic stainless steels corresponding to 304 or 316 have high quantities of nickel and chromium. The chromium combines with the oxygen before the iron is ready to which types a chromium oxide layer. This layer may be very corrosion resistant which prevents rust formation and protects the underlying metallic. On the opposite hand, ferritic or martensitic stainless steels could also be susceptible to rust because they include less chromium.
For instance, grade 316 stainless-steel can stand up to caustic solutions and corrosive functions corresponding to vapor degreasing or many different elements cleansing processes. Another popular excessive-performing alloy, grade 304 stainless steel is a durable materials when it comes to 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). However, the closer grade 304 chrome steel reaches its melting level, the more tensile strength it loses.
- Unlike carbon steel, stainless steels don’t suffer uniform corrosion when exposed to wet environments.
- The minimal 10.5% chromium in stainless steels supplies resistance to roughly seven-hundred °C (1,300 °F), whereas 16% chromium supplies resistance up to roughly 1,200 °C (2,200 °F).
- Other gases, similar to sulfur dioxide, hydrogen sulfide, carbon monoxide, chlorine, also attack chrome steel.
- Type 304, the most typical grade of chrome steel with 18% chromium, is resistant to roughly 870 °C (1,600 °F).
Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum offers 316 better total corrosion resistant properties than Grade 304, notably larger resistance to pitting and crevice corrosion in chloride environments.
Due to the addition of molybdenum, grade 316 chrome steel is more corrosion resistant than similar alloys, such as 304 chrome steel. This reduces pitting from chemical environments and permits grade 316 chrome steel to be used in extremely acidic and caustic environments that would in any other case eat away at the steel.
How can I tell if my stainless steel is 304 or 316?
Stainless 316 is made up of 16% chromium, 10% nickel and 2% molybdenum. The two steel grades are comparable in appearance, chemical makeup and characteristics. Both steels are durable and provide excellent resistance to corrosion and rust.

The elevated nickel content and the inclusion of molybdenum makes grade 316 stainless steel a bit costlier than grade 304 per ounce of fabric. But where grade 316 stainless proves superior is its increased corrosion resistance—particularly in opposition to chlorides and chlorinated solutions. This makes grade 316 stainless notably desirable for functions the place publicity to salt or other highly effective corrosives is a matter.
