Hey Guys Is the type of metal we're heating up ever properly looked into? I feel it gets overlooked. I have read and watched every video and article online regarding it. I have always used kanthol and just started using SS316l. I used to glow my kanthol but don't go beyond a full glow with my SS and usually stick to around 60 watts. Is there a danger in heating metal? Advice? A safest metal?
