Stainless Steel 347 / 347H Pipe Fittings Manufacturer

Katariya Steel is a leading manufacturer and supplier of Stainless Steel 347/ 347H Pipe Fittings. All products are manufactured in line with international standards, using premium quality materials and craftsmanship. A strict quality check is imposed on these products before they are dispatched.

Stainless Steel 347/347H pipe fittings are made of stainless steel which has excellent corrosion and oxidation-resistant properties. They are austenitic in nature. The corrosion resistance of stainless Steel 347/347H pipe fittings is comparable to that of 304. Stainless Steel 347/347H pipe fittings can be used in applications which require usage at temperatures ranging between 800 degrees Fahrenheit to 1500 degrees Fahrenheit. Stainless Steel 347/347H pipe fittings are stabilized, so they are less susceptible to intergranular corrosion, whereas unstabilized alloys like 304 are vulnerable to intergranular assault. In this temperature range. Stainless Steel 347/347H pipe fittings are well suitable for high-temperature applications because of their strong mechanical qualities. Stainless Steel 347/347H pipe fittings have better creep and stress rupture qualities than stainless Steel 304/347L pipe fittings, which could be used in situations where sensitization and intergranular corrosion are a problem.

Although stainless steel 347/347H pipe fittings cannot be toughened by heat treatment, they can be improved by cold reduction. Stainless Steel 347H pipe fittings are a higher carbon content version of Stainless Steel 347 pipe fittings that provide increased high-temperature strength.

Physical and mechanical qualities like as tensile strength, modulus of expansion, yield strength, density, hardness, ultimate tensile strength, electrical conductivity, electrical resistivity, thermal conductivity, and proof stress are all designed into these pipe fittings. They are used in a wide variety of applications like Chemical Processing, food processing (equipment and storage), petroleum refining (fluid catalytic cracking units, polythionic acid service), pharmaceutical production, waste heat recovery, etc.
