P: in the ordinary stainless steel, they are all impurity elements, but their harmfulness in austenitic stainless steel is not as significant as that in general steel. Therefore, the content can be allowed to be higher. If some data is up to 0.06%, it is beneficial for smelting control. Some of the manganese containing austenite steel can reach 0.06% (such as 2Crl3NiMn9 steel) to 0.08% (for example, Cr14Mnl4Ni steel).
The strengthening effect of steel with phosphorus, phosphorus is also as the alloy age hardening stainless steel, PH17 steel 10P (containing 0.25% P) is PH - HNM steel (containing 0.30 P) etc..

Sulfur and selenium: in general stainless steel is also often an impurity element. But adding 0.2~0.4% of sulphur to stainless steel can improve the cutting performance of stainless steel, and selenium also has the same effect. Sulfur and selenium to improve the cutting performance of stainless steel, because they reduce the toughness of stainless steel, such as 18 8 Cr Ni stainless steel impact value up to 30 kg / cm 2. The impact value of 18-8 steel (0.084%C, 18.15%Cr, 9.25%Ni) containing 0.31% sulfur is 1.8 kg / sq cm; it contains 0. The impact value of 22% selenium 18-8 steel (0.094%C, 18.4%Cr, 9%Ni) is 3.24 kg / sq cm. Sulfur and selenium both reduce the corrosion resistance of stainless steel, so they are used as the alloying elements of stainless steel.
Rare earth elements: rare earth elements are used in stainless steel, and the main reason is to improve the performance of the process. For example, adding a small amount of rare earth elements to Crl7Ti steel and Cr17Mo2Ti steel can eliminate the bubbles caused by hydrogen in the ingot and reduce the cracks in the steel billet.

The addition of rare earth elements (cerium lanthanum alloy) in austenite and austenitic stainless steel with 0.02~0.5% (cerium lanthanum alloy) can improve the forging properties. There was a kind of austenitic steel containing 19.5% chromium, 23% nickel and molybdenum, copper and manganese. Because the hot processing technology can only produce castings in the past, after adding rare earth elements, it can be rolled into various profiles.
