Carbon tool steel
According to GB/T13304 "Steel Classification" Part 1 "classification according to chemical composition of steel", the negative is non-carbon tool steel. Should be standard in accordance with Part 2 "steel quality level and the principal and the use of key performance characteristics of classification" is a special quality carbon tool steel, non-alloy steel.
Use
For the production of cutting tools, molds and measuring the carbon steel. Compared with the alloy tool steel, and its good processability, low cost, using a wide range of tools for the production of it in a larger amount. Carbon tool steel cutting into carbon steel, carbon tool steel and carbon steel gauge. Cutting means for the production of carbon steel cutting tools, carbon tool steel, carbon tool steel means for the production of cold, hot working dies of carbon tool steel, carbon steel measuring means measuring tools for the production of carbon tool steel .
T10 is the most common form of carbon tool steel, toughness, moderate, low production costs, the hardness after heat treatment can achieve 60HRC or more, but the low hardenability of this steel, and poor heat resistance (250 ℃), used for manufacturing hand tools and other simple tools. Here's a brief introduction T10 heat treatment process: Common Instrumentation: thermoelectric thermometer, the temperature box resistance furnace.
Ordinary annealing temperature 760 ~ 780 ℃, furnace cooling. After annealing, the hardness of steel is substantially reduced.
Normalizing the heating temperature 820 ~ 840 ℃, air-cooled.
High-temperature tempering heating temperature 650 ~ 700 ℃.
Quenching quenching medium: oil, heating temperature: 790 ℃, hardening methods: straight-style knife for small vertical section generally slow down.
Tempering temperature of 150 ℃, the hardness 62HRC, but easy to chipping; commonly used temperature of 200 ~ 250 ℃ ~, hardness 55 ~ 60HRC.
These are generally plants of the T10 heat treatment process conditions. Because the security broadsword generally carried out in the cottage, there is little instrumentation, mainly have to rely on Cutler and visual experience.
