Heat Resistance
Heat resistance material:Stainless, Heat-resistant steel, Ceramic
Ceramic has Heat resistance and Abrasion resistance characteristics, however low impact resistance and expensive.
Heat resistance and Abrasion resistance
※We recommend the ‘15MH’ for under 500℃.
The above chart of Heat resistance and Abrasion resistance.
