304H S30409 1.4948 Stainless Steel Tube Fittings

304H/X6crNi18-10/1.4948 Stainless Steel Pipe Fittings Wrought austenitic steel Butt-welding

"zheheng steel" produces and supply 304H/X6crNi18-10/1.4948 Stainless Steel Pipe Fittings ., Non-standard pipe fittings are also produced according to customer requirements. The company strictly implements ASTM B16.9 / B16.5,ASTM A403 SH3408, SH3409, DIN2605, EN10253, BS1965, JISB2312 and other standards for production. The materials used are special steel materials such as 304H, 304L, 321H, 316L, 317L, 310S and duplex steel 2205/31803, 904L, WP347H, WP316Ti.

304H is 304 heat-resistant steel.

According to their properties, heat-resistant steel can be divided into two types: oxidation-resistant steel and heat-strength steel. Anti-oxidation steel is also referred to as skinless steel. Hot-strength steel refers to steel that has good oxidation resistance at high temperatures and has high high-temperature strength. Heat-resistant steel can be divided into austenitic heat-resistant steel, martensitic heat-resistant steel, ferritic heat-resistant steel and pearlite heat-resistant steel according to its normalizing structure.
For 304 stainless steel, the Ni element in its composition is very important, which directly determines the corrosion resistance of 304 stainless steel and its value.

The most important elements in 304 are Ni and Cr, but they are not limited to these two elements. The specific requirements are defined by product standards. A common judgment in the industry is that as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be considered as 304 stainless steel. This is why the industry calls this type of stainless steel 18/8 stainless steel. In fact, the relevant product standards have very clear regulations for 304, and these product standards have some differences for different shapes of stainless steel.

Products description:

Why choose us:

1. All pipe fittings are strictly implemented in accordance with the standards, accept any third-party inspection, and return service.
2. Before leaving the factory, 100% dimensional inspection, 100% spectral test, mechanical and mechanical performance test, pickling, pickling process are mainly aimed at the removal of surface grease and harmful substances, complete surface passivation to prevent oxidation. Some suppliers have not implemented ( Because the surface is not visible to the naked eye after sandblasting) annealing and solid solution (heat treatment), many goods on the market are not heat-treated. When the pipe fittings are in some cold or hot environments, the seam will slowly crack if it is not heat-treated. This process is invisible to the naked eye, surface sanding (many relatively inexpensive processes on the market), bevel ends, etc.
3. Normally, the individual weight of our company's pipe fittings is heavier than that on the market, (Ensure the back arc thickness) to avoid the parts of the same wall thickness that cannot be seen by the naked eye after the processing The pressure is guaranteed, because many suppliers choose the material to the maximum limit in order to minimize the cost.
