Your Safe Landing, Courtesy of H11 Tool Steel Bolts

Chromium tool steels, also called H series steels (H1 through H19), have a balanced alloy content and suffer minimal distortion during hardening. Tool steels get their name because they are ideally suited for use as tools. This is due to their unique toughness, abrasion resistance, and their ability to resist deformation even at extreme temperatures and under extreme stress.

H11, H12 and H13 are the most commonly used varieties. H11 tool steel bolts are made of between 4.75% and 5.25% chromium. Its machinability rate is roughly 75% that of W group tool steels.

Benefits of H11 tool steel bolts in Aerospace
