Precipitation hardening stainless steel refers to a type of high strength stainless precious metal, PH steel, which adds different types and quantities of strengthening elements within the basis of the chemical composition of metal and precipitates different styles and quantities of carbides, nitrides, carbonitrides and intermetallic compounds through precipitation hardening practice, which not only boosts the strength of steel but also maintains sufficient toughness. Based on the metallographic structure belonging to the matrix, precipitation hardening steel can be divided straight into three types: martensitic, Semi-austenitic in addition to austenitic.
Precipitation hardening stainless can obtain a class of stainless with high strength, toughness and corrosion resistance with the addition of hardening elements alone or in combination.
According to the content of main alloying elements in steel along with the hardening elements added, the steel could be divided into four categories, namely:
(1) Martensite precipitation hardening metal, which generally contains 0. 1% less carbon. By adding hardening aspects (copper, aluminium, titanium and aluminium, etc. ) to strengthen, to make up for that lack of strength. Chromium content is generally higher than 17%, and appropriate nickel is included with improve corrosion resistance.
(2) The maraging stainless steel contains just around 0. 03% carbon to make sure the toughness, corrosion challenge, weldability and workability on the maraging matrix, and 12% chromium to guarantee corrosion resistance. In improvement, alloy element drill is added to improve the heat treatment consequence of steel.
(3) Semi-austenitic, my spouse and i. e. transitional precipitation hardening steel, contains not less compared to 12% chromium. The section steel having low carbon content plus aluminium as its major precipitation hardening element includes better comprehensive properties than martensitic precipitation hardening stainless steel.
(4) Austenite precipitation hardening stainless steel is a type of stainless steel with stable austenite structure in quenching along with aging state. It is made up of nickel (more than 25%) as well as manganese, and chromium (more as compared with 13%). In order to make sure good corrosion resistance and oxidation resistance, titanium, aluminium, vanadium or phosphorus are generally added as precipitation hardening features, and trace elements just like boron, vanadium and nitrogen are included in obtain excellent comprehensive attributes.
Precipitation hardening stainless steel has high strength, substantial toughness, high corrosion resistance, high oxidation resistance, outstanding formability, weldability and different comprehensive properties.
It is trusted in advanced industry and also civil industry, such as typical precipitation hardening stainless 17-4PH. It can be familiar with make structures below 370 D, requiring corrosion resistance, put on resistance and high strength.
