Alloyed steels are generally supplied in the quenched and tempered state, with specific mechanical characteristics for each application.
Steel produced at the quenched and tempered state according to the United States standard ASTM A-193, widely used for linkages and bolts destined for the oil industry. It is analytically similar to 42CrMo4 of the European standard. The B7M version, produced at higher temperatures, has slightly lower resistance characteristics but greater plasticity.
A steel produced at the quenched and tempered state according to the United States standard ASTM A-193, it is used for linkages and bolts destined for the oil industry. Analytically similar to the 40CrMoV4-6 type of the European standard EN 10269. It has greater temperability than the previous type thanks to the higher amount of alloy elements.
Reference SheetSteel produced at the quenched and tempered state according to the United States standard ASTM A320, used for linkages and bolts destined for use at low temperature in the oil industry. It has mechanical characteristics similar to the A193 B7 type, but additionally guarantees resilience values at low temperature. The B7M version, produced at higher temperatures, has slightly lower resistance characteristics but greater plasticity.
