Stainless steel product features
Nov 29, 2016

Usually stainless steel pipe has three characteristics: weldability, corrosion resistance, polishability (BQ)


Application requirements for welding performance also varies. Type of cutlery on the welding properties not required generally, even including some kind of enterprise. But most products need good welding properties of raw materials, two types of cutlery, mug, steel pipes, water heaters, drinking fountains, etc.

Corrosion resistance

Most stainless steel products requirements resistance corrosion performance good, stainless steel tube as one or two class tableware, and kitchen, and water heater, and water machine,, some abroad businessman on products also do resistance corrosion performance test: with NACL water solution heating to boiling, a time Hou pour off solution, wash NET drying, said weight loss, to determine by corrosion degree (Note: products polishing Shi, for Emery cloth or sandpaper in the contains Fe of components, will led to test Shi surface appeared rust)

Polishing (BQ)

Stainless steel products generally have polished the processes in production, only a few products, such as water heaters, drinking fountains liner does not require polishing. This requires polishing of the material very well. Factors affecting properties of polished mainly the following points:

① material surface defects. Such as scratches, pits, acid, etc.

② stainless steel raw material issues. Hardness is too low, polishing, it is not easy to throw light (bad BQ), and hardness is too low, the surface appears orange peel phenomenon in deep drawing, thus affecting the BQ. High hardness BQ is relatively good.

③ After deep drawing of product, distortion great regional and RIDGING can make small black spots on the surface, which affects the BQ.
