Application:
136R is suitable for plastic molds, and has better antirust properties for the molds used under wet environment. It is mainly used for making of the high-quality transparent plastic molds, e. G. Sunglasss and optical instruments.

Characteristics:
136R is an alloy that is developed by absorbing the adventages of foreign similar mirror steel like S-136 and added with fine structure element based on XF2083.
