The original design (Type A) was made of mild steel with a brim 1.5-2 inches (38-51 mm) wide. The Type A was in production for just a few weeks before the specification was changed and the Type B was introduced in October 1915. The specification was altered at the suggestion of Sir Robert Hadfield to a harder steel with 12% manganese content, which became known as "Hadfield's steel", which was virtually impervious to shrapnel balls hitting from above. Ballistically this increased protection for the wearer by 10 percent. It could withstand a .45 caliber pistol bullet traveling at 600 feet (180 m) per second fired at a distance of 10 feet (3.0 m). It also had a narrower brim and a more domed crown
