CARBON STEEL
This grade of carbon steel (ASTM A216 grades WCB, WCC) is commonly found in valves and is used primarily for high pressure and/or high temperature services. They oxidize rapidly and have a poor corrosion resistance. Because of this carbon steel valves should only be used in a mildly corrosive service and where the valve is full all or most of the time. Carbon steel valves can be used successfully in wastewater systems, but only in certain limited conditions.
These grades of carbon steel are commonly used for valves, flanges, fittings, and other pressure-containing parts intended for low-temperature service. These alloys are supplied in the quench and tempered state.
AISI 1020 has low hardenability properties and is a low tensile carbon steel with good machinability and good weldability. Due to its low carbon content, it is resistant to induction hardening or flame hardening. Due to lack of alloying elements, it will also not respond to nitriding.
AISI 1030 steel is a higher carbon steel, and has moderate strength and hardness and can be supplied in the normalized or quenched and tempered condition. It also has fair machinability, ductility and good weldability.
AISI 1040 carbon steel has high carbon content and can be hardened by normalizing and tempering and responds readily to induction or flame hardening.
LOW ALLOY STEEL
- ASTM A148 Grade 80-40 to 130-115
- ASTM A217 - WC5, WC6, WC9
- ASTM A487 Grades 1-10
- ATSM A487 CA-15 / CA6NM
These grades cover carbon steels and alloy steels that are subjected to higher mechanical stresses than A27 and A216 specifications. M.A. Steel can supply grades up to and including 130-115 material with varying chemistries all in the water quenched and tempered state.
Castings made out of these grades are typically used in valves, flanges, fittings, and other pressure-containing parts intended primarily for high-temperature and corrosive service. Typical heat treatment consists of normalizing and tempering.
Castings made to this ASTM specification are supplied in the water quenched and tempered condition and are suitable to both pressure containing parts and are similar in chemistry and properties to the standard 4130, 8630, and 4320 steels which are commonly found in a lot of oil field castings.
Typical castings made in these materials include impellers and pump housings.
HIGH ALLOY STEEL
- ASTM A351 - CF3, CF3M, CF8M, HK40, CD4MCu, CG8M
- ASTM A297 - HH, HK, HT, HP
- ASTM A560 - 50Cr-50Ni, 50Cr-50Ni-Cb
- ASTM A128 - Manganese Steel
Austenitic steels are non-magnetic stainless steels that contain high levels of chromium and nickel and low levels of carbon. Known for their formability and resistance to corrosion, austenitic steels are the most widely used grade of stainless steel. Castings include some pump parts, impellers, and boiler applications.
These castings are typically used in a heat resistant environment for boilers and tube sheets and are supplied in the as-cast condition.
Castings made to this specification are designed for elevated temperatures in conjunction with a corrosive environment. Typical castings include tube hangers, spacers, and supports.
These steels are typically used for high wear applications especially in the mining and oil-sands industries.
