High corrosion resistance

Nickel and chrome are important elements of in stainless steel. The nickel content of SUS304 stainless steel is as high as 8-10.5%; the chromium content reaches 18-20%, 100% up to national standard. The stainless steel property is more stable, and the corrosion-resistance is higher.

High glossiness

Special lengthened annealing process is adopted, so the glossiness is higher.

Better stretch bending strength

Selects quality raw materials with higher contents of nickel, chrome and copper, etc. so the corrosion-resistance and technological properties are greatly improved. Work hardening is reduced, and deep stamping, bending and such processability under normal temperature is better.

The food hygiene uses the tube

Material: 304, 304l, 316,316l.

Application: Milk and food industry, pharmaceutical industry, industries with special internal surface requirements.

Technological features: Inner wall surface roughness RA exceeds 0.2, with least wall leftovers, easy to clean, preventing bacteria growing. Electropolishing has the function of passivation, inner wall is highly corrosion-resistance.

Testing methods: Transverse and longitudinal flattening, reverse flattening, water pressure testing, mechanical property testing, inner surface roughness testing

Application: 201 and 202 for lightly polluted environment; 304 for environment with medium pollution; 316 and 316L for heavily polluted environment, coastal environment with salt fog, environment with serious acid rain; 430 for indoor dry environment; 321 for industry applications.

The heat exchanger use the tube

Material: 304, 304L, 316, 316L, 210, 202.

Application: Heater, boiler, heat exchanger, condensation.

Technological features: Inner weld pass leveling, solution, pickling.

Performance features: Pipe inner wall is smooth, with low resistance in water delivery, capable of enduring high water current erosion. After solution, weld pass and basic mechanical properties, corrosion-resistance are good, with good performance in deep processing.
