Stainless steel thick wall pipe 304
Grade description:
The grade 304 and 304L of stainless steel pipes are an austenitic SS which are the most versatile as
well as highly used types of stainless steel. This grade exhibits outstanding corrosion resistance to a
broad range of corrosive environments. Both of the stainless steel grade types offer very good
machinability with excellent weldability features with or without the addition of any filler materials.
Product description:
The Stainless Steel 304/304L Pipes Tubes have a very high erosion resistance than the unvarying steel
type and are highly used for the principal reason that of the easiness that it is designed into numerous
shapes. It also comprises of high tensile strength with flawless fabrication, sturdy feature in it. The
SS 304/304L Pipes and tubes are excellent in its welding and forming properties.
All or products are well tested and go through several quality checks while the development of the
product to maintain the superior quality of the product. Stainless Steel 304/304L Pipes
Tubes are packed in wooden boxes to avoid any sort of damage to it.

This grade is commonly known as “18-8” stainless steel, as it contains 18% chromium and 8% Nickel. 304 stainless steels are widely used to resists ordinary rusting in most applications. Both grades 304 and 304L can be made available seamless pipes and welded pipes form. We mainly have ready stock of 304/304L pipes. Grade 304L is widely used by the fabrication industry and all standard welding techniques can be used on 304L pipes. The “L” in 304L stands for “Low Carbon Content”, indicating a maximum carbon content of 0.035%. The “H” in 304H stands for “High Carbon Content”, indicating carbon content of not less than 0.04% and not more than 0.10%.
The tensile and yield strength of 304H stainless steel is greater than 304L, as the higher carbon content increases its strength. Stainless steel 304H grade pipes are widely used for manufacturing boilers, pressure vessels and heat exchangers for fertilizer plants, chemical plants, petroleum refineries, and power generation plants.
