The heat treatments of U stainless steel heat exchanger

When talking about the heat treatment of austenitic U-shaped stainless steel tubes, most people think it’s not necessary because of sensitization and high solution treatment temperature, it is easy to cause deformation of the pipe. In fact, the heat treatment of Austenitic stainless steel is inevitable, heat treatment can not change the structure of stainless […]

The polishing treatment on stainless steel tube

The polishing treatment of stainless steel tubes is actually a surface grinding process, through the instrument and stainless steel tube surface friction to obtain a bright surface. Stainless steel tube outside polishing is used to cut the surface with different coarse particle size linen wheel to obtain the bright surface, and the internal polishing is […]

The weight chart of stainless steel square and rectangle tube

The stainless steel offers good corrosion resistance against most common chemical corrodents and industrial atmospheres. The stainless square or rectangle tubes have the advantages of long service life, good corrosion resistance and lightweight can be used in industrial piping, automotive, instrumentation, medical and construction industries, such as stair handrails, railings, partitions, bicycles, medical equipment, cars […]

Is Alloy20 a nickel-based alloy or stainless steel?

Alloy20 (N08020) is an Austenitic nickel-iron-chromium-based superalloy with excellent resistance to total, intergranular, pitting and crevice corrosion in chemicals containing chlorides, sulfuric acid, phosphoric acid and nitric acid. Its corrosion resistance is good between 316L and Hastelloy, and it is not as good as 316L stainless steel in some amine solutions because it is easy […]

The theoretical weight of 304 stainless steel pipe elbow

Stainless steel pipe fittings are extensively used in the manufacturing industries for its durability and cost-effectiveness. It has many advantages over the traditional pipe fittings that make it more preferable than any other. The cost-effectiveness of the alloy products greatly contributes to their wide application. Besides this, it helps in the maintenance of the pipe […]

What’s the duplex stainless steel used for?

Duplex stainless steel refers to the stainless steel that have each 50% of ferrite and austenite , the general content of the less phase is at least 30%, it has both the characteristics of austenite and ferrite stainless steel. Compared with ferrite, it has higher plasticity, toughness, no room temperature brittleness, intergranular corrosion resistance and […]
