Most of the stainless steel sanitary pipe products are made of high quality imported 304 stainless steel to ensure that the pipes are hygienic and non-toxic, and fully comply with the national GB/T17219-2001 "Safety Evaluation Standard for Drinking Water Distribution Equipment" and CJ/T151-2001 "Thin-walled stainless steel water pipes" main indicators requirements. Mainly used in water supply and drainage, hot water, cold water, heating, drinking water.
As a widely used steel, 304 stainless steel sanitary pipe has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; stamping, bending, hot workability, no heat treatment hardening phenomenon (non-magnetic, use temperature -196 °C~800°C). These pipes can be used for household items (1, 2 types of tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molded products), medical equipments, building materials, chemicals, food industry, agriculture, ship parts.
304L stainless steel sanitary pipe belongs to low carbon austenitic stainless steel and acid resistant steel. It has general anti-intergranular corrosion resistance, excellent corrosion resistance and cold working stamping performance. It has strong corrosion resistance to oxidizing acid (such as nitric acid). Alkaline solutions and most organic and inorganic acids also have some corrosion resistance. This steel is suitable for the manufacture of deep-drawn parts, as well as acid pipelines, acid storage tanks, etc. 304H has good corrosion resistance and weldability, and its thermal strength is good.
