Stainless steel water pump is food hygiene, industrial chemical transmission of important liquid discharge equipment, the following Shenlong pump technology to pump users and pump selection of enterprises and institutions talk about stainless steel pump analysis.
Stainless steel pump in accordance with the different components of stainless steel can be divided into: stainless steel 201, stainless steel 304, 316 stainless steel, 316L stainless steel.
201 stainless steel, with acid, alkali, high density, polished no bubbles, no pinhole and other characteristics, is the production of various cases, strap back cover high-quality materials. Mainly used for decorative tubes, industrial pipe, a number of shallow tensile products.

Corrosion in the atmosphere, if it is industrial atmosphere or heavily polluted areas, you need to clean in time to avoid corrosion. Suitable for food processing, storage and transportation. Has a good processing performance and weldability. Plate heat exchanger, bellows, household goods, building materials, chemicals, food industry. 304 stainless steel for the national recognition of food grade stainless steel.
304 stainless steel chemical grades 06Cr19Ni10 old grades (0Cr18Ni9) containing 19% chromium, nickel 8-10%.
304 stainless steel is the most widely used stainless steel, heat-resistant steel. For food production equipment, general chemical equipment, nuclear energy.

316 stainless steel, 18Cr-12Ni-2.5Mo because of the addition of Mo, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used under harsh conditions; excellent work hardening (non-magnetic). Machinery, equipment, chemicals, dyes, paper, oxalic acid, fertilizers and other production equipment; photography, food industry, coastal facilities, rope, CD rods, bolts, nuts. 316 stainless steel Chemical composition: C≤0.08, Si≤1.00, Mn≤2.00, P≤0.035, S≤0.03, Ni: 10.0-14.0, Cr: 16.0-18.5, Mo: 2.0-3.0.316 Stainless steel Mechanical properties, tensile strength Strength (Mpa) 620MIN, yield strength (Mpa) 310MIN, elongation (%) 30MIN, area reduction (%) 40MIN, 316 stainless steel density 8.03g / cm3, austenitic stainless steel generally use this value
316L stainless steel, the scope of pipeline, heat exchangers, food industry, chemical industry, watches and clocks, and other industries.
