Stainless steel ring chain lever hoist processing technology

In fact part of the stainless steel, both stainless nature, there are acid resistance, corrosion resistance. Stainless steel and corrosion resistance is due to chromium-rich oxide film on the surface (passivation film) formation. This stainless steel and corrosion resistance is relative, introduce you to the following  hoist equipment  steel processing technology details, for you to understand.



Tests showed that steel in the atmosphere, water and weak nitric acid medium and oxidizing medium, the corrosion resistance of chromium steel with the increase of the water content increased, when the chromium content reaches a certain percentage, the occurrence of corrosion resistance of steel mutation, that is, from rust to rust, never corrosion to corrosion. Many classification of stainless steel. The organizational structure at room temperature classification, martensitic,wire rope winch austenitic, ferritic and duplex stainless steel; by major chemical composition can basically be divided into chromium stainless steel and chrome-nickel stainless steel two systems; by Purpose then there is resistance to nitric acid stainless steel, acid-resistant stainless steel, water-resistant stainless steel, etc., can be divided into types by corrosion-resistant stainless steel pitting, stress corrosion of stainless steel, resistant to intergranular corrosion of stainless steel, etc.; classification according to features can be divided into no magnetic stainless steel, free cutting steel, low temperature steel, high-strength stainless steel and so on.
Because stainless steel has excellent corrosion resistance, formability, compatibility, and in a wide temperature range and other characteristics of strength and toughness,manual block so in heavy industry, light industry, household items and architectural decoration industry and other industries have access to a wide range of applications .
