such as typical precipitation
English Public
Precipitation hardening s / s refers to a type of high strength stainless metal, PH steel, which adds many kinds and quantities of strengthening elements to the basis of the chemical composition of steel and precipitates different kinds and quantities of carbides, nitrides, carbonitrides along with intermetallic compounds through precipitation hardening process, which not only elevates the strength of steel and maintains sufficient toughness. Determined by the metallographic structure with the matrix, precipitation hardening stainless steel can be divided in to three types: martensitic, Semi-austenitic and also austenitic.
Precipitation hardening metal can obtain a class of metal with high strength, toughness and corrosion resistance by adding hardening elements alone or in combination.
According towards content of main alloying elements in steel along with the hardening elements added, the steel is usually divided into four types, namely:
(1) Martensite precipitation hardening metal, which generally contains 0. 1% a smaller amount carbon. By adding hardening aspects (copper, aluminium, titanium plus aluminium, etc. ) to help strengthen, to make up to the lack of strength. Chromium content is generally higher than 17%, and appropriate nickel is included to improve corrosion resistance.
(2) The maraging stainless steel contains just around 0. 03% carbon to ensure the toughness, corrosion resistance, weldability and workability from the maraging matrix, and 12% chromium to be sure corrosion resistance. In accessory, alloy element drill is added to further improve the heat treatment influence of steel.
(3) Semi-austenitic, my spouse and i. e. transitional precipitation hardening steel, contains not less in comparison with 12% chromium. The section steel together with low carbon content in addition to aluminium as its major precipitation hardening element possesses better comprehensive properties as compared with martensitic precipitation hardening stainless steel.
(4) Austenite precipitation hardening stainless steel is a type of stainless steel with stable austenite structure in quenching and also aging state. It includes nickel (more than 25%) as well as manganese, and chromium (more as compared to 13%). In order to be sure good corrosion resistance as well as oxidation resistance, titanium, aluminium, vanadium or phosphorus tend to be added as precipitation hardening components, and trace elements such as boron, vanadium and nitrogen are included to obtain excellent comprehensive houses.
Precipitation hardening stainless iron has high strength, substantial toughness, high corrosion resistance, high oxidation resistance, fantastic formability, weldability and alternative comprehensive properties.
It is key in advanced industry and civil industry, such as typical precipitation hardening s / s 17-4PH. It can be employed to make structures below 370 C, requiring corrosion resistance, have on resistance and high energy.
We offer our customers an array of stainless steel custom solutions, including hot rolled metallic profiles, cold drawn metallic profiles, steel wire rod, special-shaped steel tubes, s / s profiles, small and large precision steel, non-standard metallic products.
