Special steels conforming to the ASTM American standards
Steels for use in oil and gas components
The materials of this category, non-alloyed and alloyed steels adhering to some ASTM American standards, are used for the production of flanges, fittings and linkages for the oil and gas industry.
Alloyed steels are generally supplied in the quenched and tempered state, with specific mechanical characteristics for each application.

Rodacciai Mark
A105
K105Steel name
A105
A carbon steel in accordance with US standards, it has a very high resilience even at low temperatures. Used for flanges, fittings, and construction in general.

Rodacciai Mark
RK1 B7
A193 B7MSteel name
A193 B7 - A193 B7M
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.

Rodacciai Mark
A193
B16Steel name
A193 B16
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.

Rodacciai Mark
A320 L7
L7MSteel name
A320 L7 - A320 L7M
Steel 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.

Rodacciai Mark
A320 L43
Steel name
L43 - 4340
Steel generally used in large size bolts up to 4” that require high performance of resilience at low temperatures , it has the same mechanical characteristics as the ASTM A320 L7 quality
