Stainless steel pipe is used for transporting liquids and gasses in a wide range of industries including mining, oil, natural gas, automotive, and aviation. We carry a wide range of stainless steel pipe schedules: 304 Sched. 5, 304 Sched. 10, 304 Sched. 40, 304 Sched. 80, 316 Sched. 10, 316 Schedule 40, and 316 Sched. 80. Our stainless steel pipe for sale is available in standard sizes, or you can have it custom cut to your specifications.

It is often said that the phase balance of duplex stainless steels is "50-50", which corresponds to the amount of austenite and ferrite. Strictly speaking, this is not true, as the ferrite content in modern duplex stainless steels is around 40% - 50% and the rest is austenite.

Stainless steel can be roughly divided into flat steel and concave-convex steel. The flat steel plate can be divided into three categories: mirror steel plate with surface light reflectivity greater than 90%; The reflectivity is 50%~90% of the light plate; Matte steel plate with reflectivity less than 50%.

Stainless steel is initially by British scientists Henry cabral, doing research on the improvement of weapons found and the stainless steel in which the research has a strong dirt, acid resistance, corrosion resistance, wear resistance, no radioactive environmental products in developed some stainless steel products to pop up to now and slowly instead of the other material products.From material selection to molding, the stainless steel products cast by us have gone through 33 years of process processing. The surface technology adopts stainless steel primary color mirror polishing.

How to identify the quality of stainless steel sinks?1. Thickness of water tank steel plate: The high-quality water tank adopts imported 304 stainless steel plate with a thickness of 1mm, while the ordinary low-grade water tank adopts 0.5mm-0.7mm. The method of identification can be determined from the weight and whether the surface is flat.2. Anti-noise treatment: The bottom of the high-quality sink is sprayed or glued with rubber sheets and does not fall off, which can reduce the sound caused by the impact of the water from the faucet on the bottom of the basin, and play a buffering role.3.

1, Corrosion resistance, non-flammable, non-toxic and tasteless.  2, Good wear resistance, long service life, stainless steel perforated mesh wear resistance for ordinary sieve plate 3 to 5 times, for ordinary rubber sieve plate more than 5 times.  3, The total cost is low, although the same specification (area) of stainless steel perforated plate than ordinary sieve plate high one-time investment (about 2 times), but because the life of stainless steel perforated plate is 3 to 5 times the ordinary sieve plate, and less maintenance and replacement, so the total cost is not

Although stainless steel plates account for a relatively small proportion of world steel consumption, they are still vital to specific manufacturing industries such as the energy and food processing markets. At present, the global consumption of stainless steel plate materials is continuously increasing.In recent years, technological progress has significantly improved the quality of plasma cutting of stainless steel plates. These advancements span a range of thicknesses and have reached 6.25 inches.The early plasma cutting consumes a high current and the cutting speed is also very slow.
