INLAND HI-FORM Steels are a low-carbon, low or intermediate-manganese, low-sulfur, aluminum-killed, fine-grain, columbium and/or phosphorus-bearing series of high-strength steels providing greatly enhanced forming and bending properties. These steels are furnished in minimum yield strength levels from 40,000 to 80,000 psi. They are used widely in the transportation and mobile-equipment industries.
