Supplier of ASTM A312 Standard Specification for A312 TP304H Seamless stainless steel pipes, A312 TP304H Welded stainless steel pipes, and A312 TP304H Heavily Cold Worked Austenitic Stainless Steel Pipes.
Superior Steel Overseas is acknowldeged manufacturer, supplier, distributor and exporter of Stainless Steel 304H Welded Pipe. Grade"H" in 304H stands for "High Carbon Content", indicating carbon content of not less than 0.04% and not more than 0.10%.The main advantage of SS 304H welded pipe tensile and yield strength is greater than 304L, as the higher carbon content increases its strength.Welded 304H pipeare widely used for manufacturing boilers, pressure vessels and heat exchangers for fertilizer plants, chemical plants, petroleum refineries, and power generation plants.304H stainless steel welded pipes is a strong, tough metal with high corrosion protection, high temperature resistance and the ability to be sterlized.We are specialized in supply ASTM A312 TP304H ERW Pipe after Mill Test Certificate as per EN 10204 as per 3.1/3.2 TC.These ASTM A312 TP304H EFW Pipe is widely used by the fabrication industry and all standard welding techniques can be used on 304H welding pipes.304H stainless steels are widely used to resists ordinary rusting in most applications.
The stainless steel 304H pipe possesses high corrosion resistance and it contains an appropriate amount of chromium. The chromium is responsible for forming a self-healing layer of oxide that gives stainless steel pipe their corrosion resistance properties. It also offers resistance at cryogenic temperatures. Cryogenic resistance can be easily measured by toughness or ductility at zero temperature. It has a high tensile strength at ambient temperature. It has maintained excellent toughness. The strength of the pipe is achieved through cold working and thus fabrication component receives appropriate strength. It can recollect the strength at some eminent temperature. The high chromium content helps to resist scaling at peak temperatures. The pipe offers great ductility and work hardening allow the formation of stainless steel using severe processes like deep drawing. In comparison to mild steel, it has strength double. Other known properties of SS 1.4948 Welded Pipe are heat resistant qualities, great creep strength, and high tensile yielding strength. In contrast, it offers high weldability, corrosion as well as oxidation resistance so that it performs well. It has a typical application such as commercial and home application including container and tank for a variety of solid and liquid.

1. Cutting and turning of steel material: First of all, cutting and turning of steel material, replacing the size, and finally cutting out the steel material
To determine the size of the steel used in the process.
2. Change the structure of the steel material: what needs to be done here is to change the structure of the steel material after appropriate heat treatment
Structure to ensure the correct volume of the product after the cold rolling process.
3.cold pressing processing: cold pressing processing is the most critical step in the cold rolling process, through cold pressing processing, can be realized
The originally round steel is compressed and the shape becomes extended.
4.shaping and welding: before shaping and welding, first of all, the use of precision measuring equipment to detect cold press processing
After the size of the steel material to ensure that accurate shaping and welding can be achieved.
5.surface treatment: Surface treatment is the last step of the cold rolling process, including painting, gas, polishing and electricity
Plating. The purpose of the surface treatment is to enhance its visual effect and processing properties, resulting in a quality product.
