304L pipe 18cr-8ni-Low carbon as low C 304 steel, in general, its corrosion resistance is similar to 304 steel, but after welding or after the elimination of stress, its resistance to intergranular corrosion is excellent, in the case of heat treatment, can also maintain good corrosion resistance, the use of temperature -196℃~800℃. It is used in the field of chemical, coal and petroleum industry, which has high resistance to grain boundary corrosion, and has difficult parts for heat-resisting parts and heat treatment of building materials.

Mechanical Properties

Yield Strength(MPA) ≥ 175

Tensile Strength(MPA) ≥ 480

Elongation Rate(%)≥ 40

HV ≦ 200


18cr-8ni as a widely used steel, with good corrosion resistance, heat resistance, low-temperature strength and mechanical properties, stamping, bending and other hot processing, no heat treatment hardening phenomenon (non-magnetic, the use of temperature -196℃~800℃)



Household products (1, 2 types of tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, molded products), medical equipment, building materials, chemicals, food industry, agriculture, marine components;

Stainless steel, Alloy tool steel (in thousands of points C content), such as: 1cr18ni9 1 per thousand (that is, 0.1%c), not rust c≤0.8% such as 0cr18ni9, ultra-low carbon c≤0.3% such as 0cr17ni13mo

304L Stainless Steel Tube Type

Tubes for Heat exchangers/Condenser

Performance Characteristics

Smooth pipe wall, low water conveyance resistance, can withstand high water flow rate of erosion, solid solution treatment, welding and matrix mechanical properties, anti-corrosion performance is basically consistent, deep processing performance is excellent.

Thin-walled stainless steel tube.


Mainly used in direct drinking water engineering, other requirements of higher fluid transport

Main features: Long service life, low failure rate, water leakage rate, good transportation quality, it will not precipitate harmful objects into the water, the wall of the tube is inquiry, smooth, and the resistance to water is low; cost-effective, service life of up to 100 years, no maintenance, low cost, can withstand up to tap above the high water flow rate erosion, Ming pipe laying, beautiful appearance.

Food Hygiene Pipe

Uses: Dairy and food industry, pharmaceutical industry, special internal surface requirements of the industry.

Process Characteristics

Internal welding path Leveling treatment, solid solution treatment, internal surface electrolysis polishing

Performance Characteristics

Internal surface roughness RA up to 0.2, hanging residue less, easy to clean, to prevent bacteria growth, electrolytic polishing has passivation effect, the inner wall defense performance is good.

Detection Methods 

Horizontal, longitudinal flattening, reverse flattening, hydrostatic test or eddy current testing, mechanical performance testing, internal surface roughness detection.

Fluid tube Stainless Steel tube, elaborately manufacture stainless steel inner-flat welded pipe, widely used in dairy products, beer, beverages, pharmaceuticals, biological, cosmetics, fine chemicals compared to the common sanitary pipe, its surface finish and smooth formation of the inner wall, steel plate flexibility is more outstanding, wide coverage, wall thickness uniformity, higher precision, no hemp point, good quality characteristics.
