About Stainless Steel 304H Welded Pipes
Stainless steel comes in variety of grades and each grade has its own importance. The grade 304 comes in two varieties-304 L and 304 H. it is considered as the standard stainless steel because of its distinct characteristics. This austenitic structure steel does not undergo annealing thus making it dominant in manufacturing different parts. This grade of steel finds applications in different industries because of its outstanding welding characteristics.
The 304 H grade has higher carbon content and thus is widely used in elevated temperatures. Its austenitic structure gives it excellent toughness and thus it can use at cryogenic temperatures as well. The high carbon content in Stainless Steel 304H Welded Pipes gives it various physical and mechanical properties.
The industrial applications involves working in different environments with excessive corrosive media. The materials and parts undergo different types of corrosion. Among all types the pitting, crevice and stress corrosion cracking is common. It takes place temperature above 600 C. the chloride corrosion takes place in ambient temperature where the water level is about 200mg/L. the Stainless Steel 304H Welded Pipes has excellent resistance properties against such tough environments.
Heat resistance- our welded pipes shows excellent oxidation resistance. it show resistance in intermittent as well as in continuous service to 8700C and 9250 C respectively. However, its use in 425-8600C range is strictly prohibited when resistance against any aqueous solution is desired. It is often used at temperature about 5000C where its structural and pressure containing abilities make it withstand such elevated temperature. It offers higher strength in such applications and it can withstand about 8000C temperature.
Heat treatment- our Stainless Steel 304H Welded Pipes undergoes annealing or solution treatment at 1010-11200 C without undergoing thermal treatment. It is then cool rapidly.
Advantages of our Stainless Steel 304H Welded Pipes include low costs with shorter procurement lead time. The welded pipe has small defects.
Pipe packaging at Piyush steel-
We pack these welded pipes into plastic bag. The individual piece of pipe is wrapped with materials that protect it from outer environment. Moreover the material is water proof. They are bundled with a rope of nylon. They are tagged with clear label for easy identification of product. The label contains the product ID for easy identification. The packaging is according to the standards set internationally. They are then stored in containers to avoid damage of any kind.
The product is then transported to the client’s address within the specified period. Customers can specify the product requirements and get the customized dimensions as per their needs.
