Delivery Status

Generally in the state of heat treatment delivery, the type of heat treatment in the contract noted; not noted, according to heat treatment status

316 is the United States standard under the brand. belong to the stainless steel, heat resistant, corrosion resisting steels. It is the 0cr17ni12mo2. It is better than 304 stainless steel. Corrosion resistance is better than 0cr19ni9 in seawater and other kinds of media.


316 stainless steel and 304 stainless steel from the appearance of how the difference is as follows:

Now the two most commonly used stainless steel 304,316 (or the corresponding Ude/European standard 1.4308, 1.4408), 316 and 304 in the chemical composition of the most important difference is 316 contain MO, and generally recognized that 316 corrosion resistance is better, than 304 in the high-temperature environment more corrosion resistance. Therefore, in the high-temperature environment, engineers will generally choose 316 of the material components.

[1] Mo is indeed a high-temperature-resistant substance (know what crucible is melted in gold?) Molybdenum Crucible! )。

[2] molybdenum easily reacts with high sulfur ions to generate sulfide.
