Import Black Surface Hot Work Mold Tool H13 — Buy in Bulk from Supplier in China

The Black Surface Hot Work Mold Tool H13 is a premium hot work tool steel engineered for applications requiring high red-hardness and toughness under extreme temperatures. This grade is widely used in industries such as die casting, forging, and extrusion, where tools must maintain their properties at elevated temperatures. The black surface finish provides basic protection against corrosion and wear during handling and storage.

H13 tool steel is a chromium-molybdenum-vanadium alloy known for its ability to retain hardness and strength at high temperatures, typically up to 600°C. Its composition includes approximately 0.35-0.45% carbon, 4.75-5.50% chromium, 1.10-1.75% molybdenum, and 0.80-1.20% vanadium, which contribute to its thermal stability and resistance to thermal fatigue. Standard industry classifications for H13 include AISI H13 and DIN 1.2344, with typical hardness ranging from 48-52 HRC in the hardened condition.

This product is primarily sourced by manufacturers in the automotive, aerospace, and metalworking industries, where precision and durability are critical. The steel’s water-cooled capability allows for efficient thermal management during service, reducing the risk of cracking or deformation. Buyers should confirm the exact heat treatment and machining allowances, as these can vary based on the intended use. The material is typically supplied in annealed or pre-hardened conditions to facilitate machining.
