The low carbon content is making 904L sensitization resistance by welding and it thus prevents IGC.
These SS 904L pipes and SS 904L tubes are formed by strictly using 100& pure quality of raw materials and also by using the latest technology.
Stainless steel is an alloy of iron that is resistant to rusting. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel’s resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen.
This alloy is having chemistry design for achieving thermal stability level that is superior to predecessors like B2 alloy. It is having good resistance to corrosion, pitting and stress corrosion cracking and to knife line as well as the heat affected zone attack.
The pipes are having good stress corrosion cracking and pitting resistance ability.
The pipes are phosphoric acid, acetic and formic acid resistant. Also, it to various temperature and concentrations is hydrochloric acid resistance.
The thermal stability of Hastelloy B3 pipes is superior.
Hastelloy B-3 is a nickel-molybdenum alloy with excellent resistance to pitting, corrosion, and stress-corrosion cracking plus, thermal stability superior to that of alloy B-2. In addition, this nickel steel alloy has great resistance to knife-line and heat¨Caffected zone attack.
Alloy B-3 also withstands sulfuric, acetic, formic and phosphoric acids, and other non-oxidizing media.
This nickel alloy has excellent resistance to hydrochloric acid at all concentrations and temperatures.
The use of refined technology and the modern tool has helped the producer to make the superior quality of pipes.
The product to the buyer is supplied at the comprehensive range that vary in sizes, thickness, length, ends etc.
Hastelloy B2 is also known as UNS N10665 that is corrosion resistant and solid solution molybdenum-nickel alloy.
This alloy is exhibiting good corrosion resistance at aggressive reducing media like hydrochloric acid that range of concentrations and temperatures and in medium-concentrated sulphuric acid and with limited chloride contamination.
The alloy can be used in phosphoric acid and acetic acid and a range of organic acids. Hastelloy B2 alloy is having chloride induced SCC resistance.
Hastelloy B3 pipe is significantly resistant to corrosion resistance at reducing atmosphere. Hastelloy B2 pipes are having excellent resistance to non-oxidizing acid and sulphuric acid.
Hastelloy B3 pipe has good resistance to stress corrosion cracking that is chloride induced. The good resistance to a wider range of organic acids makes Hastelloy B2 pipes a popular product.
Hastelloy B3 is molybdenum and nickel alloys family additional member with greater hydrochloric acid resistance at various concentrations and temperatures. It is withstanding formic, sulphuric and phosphoric acid as well as non-oxidizing acids.
Alloy B2 should not be used at temperatures between 1000¡ãF and 1600¡ãF as the alloy forms secondary phases that could decrease the ductility of the material.
Hastelloy B2 Round Pipes (UNS N10665) is used for most chemical process applications in the welded condition, gasoline refining.
Hastelloy B2 EFW Pipes is highly resistant to all concentrations and temperatures of hydrochloric acid.
The ASTM B622 Hastelloy B2 Seamless Pipe especially is known to exhibit excellent resistance to corrosion in aggressive reducing media such as hydrochloric acid.
The hastelloy b2 pipe suppliers in Mumbai recommend using this ASTM B622 specified B2 Hastelloy Pipe because the alloy has good resistance to chloride ion induced stress related corrosion cracking or SCC.
Controlling other alloying elements such as iron and chromium
2507 is used for Chemical process industries, heat exchangers, vessels, and piping, desalination plants, high pressure RO-plant and seawater piping, mechanical and structural components, high strength, corrosion-resistant parts.
This type of steel is excellently resistant to shearing as a result of stress corrosion, high thermal conductivity and a low thermal expansion coefficient.
The high chromium, molybdenum, and nickel levels provide excellent resistance to pitting, crevice, and general corrosion.
Super Duplex stainless steel offers the same advantages as its Duplex counterpart. The main difference between the two is that Super Duplex has a higher chromium and molybdenum content, resulting in increased corrosion resistance.
It is widely used in offshore oil and gas exploration/production and in heat exchangers in petrochemical/chemical processing.
