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.

Due to the addition of molybdenum, grade 316 stainless steel is more corrosion resistant than comparable alloys, corresponding to 304 stainless steel. This reduces pitting from chemical environments and allows grade 316 chrome steel for use in highly acidic and caustic environments that would otherwise eat away on the metallic. For instance, grade 316 stainless steel can stand up to caustic solutions and corrosive functions similar to vapor degreasing or many different elements cleaning processes. Grade 444, particularly, has a pitting resistance equal (PRE) that’s just like grade 316 austenitic stainless steel, permitting it to be used in additional corrosive outside environments.

Is duplex stainless steel magnetic?

Duplex stainless steels are typically magnetic because they contain a mixture of austenite and ferrite. The substantial amount of ferrite (which is magnetic) contributes to Duplex steels being magnetic.

It is probably the most extensively used duplex chrome steel grade and is characterised by high energy, double that of the usual austenitic stainless-steel grades. It demonstrates good fatigue strength, in addition to excellent resistance to emphasize-corrosion cracking, crevice, pitting, erosion and common corrosion in severe environments. Combining many of the helpful properties of both ferritic and austenitic steels, 2205 is probably the most widely used duplex stainless-steel grade. Its high chromium and molybdenum content material offers the chrome steel excellent corrosion resistance. The microstructure offers resistance to emphasize corrosion cracking and ensures excessive power.

Grade 316L is extra immune to carbide precipitation and can be used within the above range. Grade 316H has larger strength at elevated temperatures and is sometimes used for structural and stress-containing at temperatures above about 500 °C. If you have an software with very powerful corrosives or depends on chlorides, then paying a premium for grade 316 chrome steel is definitely value it.

2205 stainless steel

What is meant by duplex stainless steel?

SAF 2507 is a Super Duplex (Austenitic-Ferritic) Stainless Steel is characterized by – Excellent resistance to stress corrosion cracking (SCC) in chloride-bearing environments. Excellent resistance to pitting and crevice corrosion. High resistance to erosion corrosion and corrosion fatigue.

2205 stainless steel

  • It resists localized corrosion varieties like intergranular, crevice and pitting.
  • Grade 2205 chrome steel displays glorious corrosion resistance, a lot larger than that of grade 316.
  • The CPT of this type of stainless-steel is around 35°C.
  • This grade is immune to chloride stress corrosion cracking (SCC) at temperatures of a hundred and fifty°C.
  • Grade 2205 stainless steels are apt replacements to austenitic grades, especially in premature failure environments and marine environments.

Salt will even compromise the protecting oxide layer of grade 304 stainless-steel, resulting in rust. For marine functions, or processes involving chlorides, grade 316 stainless-steel is ideal.

The grade also has good resistance to emphasize corrosion cracking when uncovered to hydrogen sulphide in chloride options. This of specialty stainless steels is characterized by relatively high chromium content and the addition of molybdenum. The result is steel with wonderful corrosion and scaling (or oxidation) resistance.

The increased nickel content material and the inclusion of molybdenum makes grade 316 chrome steel a bit costlier than grade 304 per ounce of fabric. But the place grade 316 stainless proves superior is its increased corrosion resistance—significantly against chlorides and chlorinated solutions. This makes grade 316 stainless significantly fascinating for purposes the place publicity to salt or other powerful corrosives is an issue. Though the stainless steel 304 alloy has a higher melting level, grade 316 has a better resistance to chemical substances and chlorides (like salt) than grade 304 chrome steel. When it involves applications with chlorinated options or exposure to salt, grade 316 stainless steel is considered superior.

Grade 316 additionally has outstanding welding characteristics. Post-weld annealing just isn’t required when welding skinny sections. Duplex Alloy 2205 is a two-section, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to six% nickel alloyed stainless-steel.

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.
