Mar 14, 2020· The bulk of steels produce manganese of 0.15 to 0.8 per cent. Strong strength alloys also produce manganese from 1 to 1.8 per cent. The steel is fragile at around 1.5 percent of manganese content and this tendency rises until it exceeds around 4 or 5 percent of manganese content. Around this stage, a hammer's strike can pulverize the steel.
