Ultra High Strength Steel Part

DESCRIPTION

Ultra high strength steel parts signify high strength steel plates with tensile strength of 980 MPa or more.

When replacing parts made of ultra high strength steel or parts including ultra high strength steel, never perform the prohibition described below:

PROHIBITION

WARNING:

Never cut ultra high strength steel parts or perform butt welding. Violation of this prohibition causes extreme strength degradation, and the strength before damage cannot be secured.

PART REPLACEMENT

To replace an ultra high strength part, be sure to replace it by panel supply unit of ultra high strength steel part.

For the welding method, refer to Welding of Ultra High Strength Steel.
