4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. q345r jis, 4140 steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering treatment, and good low temperature impact toughness. 4140 steel is suitable for manufacturing large and medium plastic mould with certain strength and toughness.

"Mirror" refers to the surface state of q345r jis stainless steel, which is usually 8K in the industry. The common mirror stainless steel on the market is divided into 6K, 8K and 10K, which are general polishing, 6K, 8K fine grinding and 10K super fine grinding effect. The same thickness generally has no big difference, 10K mirror is brighter; the thicker the thickness, the better the effect, and the higher the processing cost.

DIN 17102 TStE285 steel plate/sheet, DIN 17102 TStE285 steel plate/sheet, under DIN standard, we can regard TStE285 steel plate/sheet as fine-grain structural steels, normalised rolled steels. q345r jis, DIN 17102 TStE285 is mainly used as ine-grain structural steels, normalised rolled steels. q345r jis, TStE285 steel plate/sheet is a hot rolled structural steels, which technical delivery conditions for normalized or normalized rolled in weldable fine grain structural steel grade. It is also regarded asEN10025:S275NL.UNE36081:AE285KT
