(1)different ingredients:
316l:C≤0.03,Si≤1.00,Mn≤2.00,P≤0.035,S≤0.03,Ni:10.0-14.0,Cr:16.0-18.5,Mo:2.0-3.0
316:C≤0.08,Si≤1.00,Mn≤2.00,P≤0.035,S≤0.03,Ni:10.0-14.0,Cr:16.0-18.5,Mo:2.0-3.0
(2)different grades:
316l: The old grade is 00Cr17Ni14Mo2, the new grade is 022C17N12M2, which is American standard TP316L, Japanese standard SUS316L
316: The old grade is 0Cr17Ni12Mo2, and the new grade is 06C17N12M2, which is American standard TP316, Japanese standard SUS316
(3)different heat resistance:
316l: The carbide precipitation resistance of 316L stainless steel is better than that of 316 stainless steel, and it can also be used in the temperature range of 800-1575 degrees
316: 316 material can be used intermittently below 1600 degrees, and in continuous use below 1700 degrees, but it is best not to use 316 stainless steel in the range of 800-1575 degrees
