Manganese Substitution Grades of Stainless Steel During World War II when nickel shortages were severe, the stainless steel industry turned to manganese as a substitute. Manganese is about half as effective in forming austenite as is nickel, so for every 1% reduction in nickel content, roughly 2% of manganese must be substituted.
Sep 08, 2020· High-manganese steel has poor thermal conductivity. If the size of the riser is too large, the excessive temperature difference between the riser and the casting in the later stage of the cooling of the casting will inevitably produce high stress, which often leads to cracks at the connection between the riser and the casting.
May 02, 2013· These high manganese grades - 200 series austenitics - were first developed in the 1930s and were expanded during World War II because of a lack of domestic nickel supplies, especially in the USA.

Jun 17, 2019· WHAT IS HIGH MANGANESE? – High Manganese (Manganal) is an austenitic (nonmagnetic), work-hardening steel. The “high” refers to the high carbon content. Typical chemical content is 11-14% manganese and 1.00-1.25% carbon.
The identification of the grinding is to grind the stainless steel on the grinder and observe the spark. If the spark is streamlined and has more dense knots, it is a high manganese or manganese nitrogen steel with higher manganese content. If there is no knot, it is chrome steel or chrome-nickel stainless steel.
Manganese increases the solubility of nitrogen and is used to obtain high nitrogen contents in duplex and austenitic stainless steels. Manganese, as an austenite former, can also replace some of the nickel in stainless steel.
