Einsatzbeispiele
- These bars have been used typically for parts 0.50 inch (12.7 mm) and under in section thickness at time of heat treatment requiring a through-hardening steel capable of developing hardness as high as 50 HRC when properly hardened and tempered and also for parts of greater thickness requiring proportionately lower hardness, but usage is not limited to such applications.
- These bars have been used typically for parts required to meet stringent magnetic inspection criteria, 19.0 mm and under in nominal thickness at time of heat treatment, requiring a through-hardening steel capable of developing hardness as high as 40 HRC when properly hardened and tempered, and also for parts of greater thickness requiring proportionately lower hardness, but usage is not limited to such applications.
- These products have been used typically for parts 12.7 mm and under in nominal section thickness at time of heat treatment, requiring a through-hardened steel capable of developing hardness as high as 50 HRC when appropriately heat treated and for parts of greater thickness but requiring proportionately lower hardness, but usage is not limited to such applications.
- This tubing has been used typically for parts, 12.70 mm and under in section thickness at time of heat treatment, requiring a through-hardening steel capable of developing hardness as high as 50 HRC when properly hardened and tempered and also for parts of greater thickness but requiring proportionately lower hardness, but usage is not limited to such applications.
- This wire has been used typically for filler metal for gas-metal-arc or gas-tungsten-arc welding of critical weldments of low-alloy steels requiring a joint capable of being heat treated to a strength level approximating that of the basis metal, but usage is not limited to such applications.
- Used typically for heat treated parts 22.22 mm and under in section thickness at time of heat treatment, requiring through-hardening to a minimum tensile strength of 1241 MPa and lower strength in heavier thicknesses, but usage is not limited to such applications.
