SA213 T12 Alloy Steel Tubing is also known as ASTM A213 T12 chrome moly tube because of the chemical makeup of Chromium (Cr) and Molybdenum (Mo). Molybdenum maintains the strength of ASME SA213 T12 square tube as well as the elastic limit, resistance to wear, impact qualities, and hardenability. Moly is the most effective single additive that enhances high temperature creep strength of ASTM A213 T12 Tubes. T12 Alloy Steel Tube (SA213 T12, Chorme-Moly) is a seamless ferritic Alloy Steel Tube for high temperature service. These T12 material including Alloy Steel T12 Tube and SA213 T12 Seamless Tube are suitable for high temperature application such as bending, flanging (vanstoning), and similar forming operations, and for fusion welding in the power industry and petrochemical plants.
We supply all T12 Chrome Moly Tubing and Alloy Steel T12 Tubing, such as T12 combustion chamber tubes, T12 heater tube, T12 header tube and T12 line pipe for main steam and reheater circuits, in a complete size range from the smallest dimension up to large heavy wall pipe in all required alloy steel grades. Long Lengths High Pressure T12 Boiler Tube and ASME SA213 T12 Seamless Tube are available in hot rolled condition up to 22.5m. Seamless ferritic alloy steel T12 Tube can be supplied to meet special surface requirements and/or close diameter and wall thickness tolerances. Cold-drawn ASTM A213 T12 Alloy Steel Tube are supplied up to 25m with close tolerances, in standard and non-standard dimensions or inside-diameter controlled.

ASTM A213 T12 Tubes Composition
ASTM A213 T12 tubes composition is that of Potassium: 0.025, Manganese: 0.30-0.61, Sulfur: 0.025, Carbon: 0.05 min - 0.15 max., Chromium: 0.80 - 1.25, Silicon: 0.50 max., and Molybdenum: 0.44 - 0.65. The Tensile Strength of A213 T12 is ksi: 60, MPa: 414. A213 T12 has a Yield of ksi: 30 and an MPa: 207. The A213 T12 Elongation in 2 in. or 50 mm, min. is 30 %. A213 T12 has a maximum Hardness Rockwell B of 85. Because of their characteristics, ASME SA213 T12 seamless tubes are ideally suited for use in collecting tubes, hot steam tube lines and super heater tubes. Plus, these tubes can also be used in permanent operations, where the wall temperatures lie up to around 1040 °F (560 °C).

Carbon steel is a large category of steel that encompasses many varying chemical compositions. Each type of carbon steel requires different considerations when welding. For example if you choose Low carbon steel to weld which is typically the most readily welded steel in a room temperature environment. These low carbon steel suitable for welding include C1008, C1018, A36, A1011 and A500. Medium carbon steel such as C1045 typically requires preheat and post-heat treatment to avoid weld cracking. High carbon steel is even more prone to weld cracking than the other two groups of carbon steel. Welding high carbon steel will most likely require very thorough preheating and post-heating processes to avoid this. It could also require special welding filler metals.
SA213 T12 Tube welding is used extensively for pipe welding, aerospace, aviation, biomedical implants, fabrication of race cars, choppers, etc.
Difference Between Low-Alloy Steel & High-Alloy Steel
Alloy Steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels.
High-Alloy Steel
High-alloy steels are defined by a high percentage of alloying elements. Stainless steel is high-alloy steel which contains at least 12 percent chromium. Stainless steel is devided into three basic types: martensitic, ferritic, and austenitic. Martensitic steels contain the least amount of chromium, and known for high hardenability, and are mainly used for cutlery. Ferritic steels contains 12 to 27 percent nickel chromium alloy and are suitable to use in automobiles and industrial equipment. Austenitic steels contain high levels of nickel, carbon, manganese, or nitrogen and usually have the highest corrosion resistance. Austenitic steels are mainly used to store corrosive liquids and mining, chemical, or pharmacy equipment.
Low-Alloy Steel
Among alloy steels, when Ni, Cr, Mo, and other alloy elements content consist of less than 10.5% are known as low alloy steels. Low-alloy steels have a much lower percentage of alloying elements, usually 1 to 5 percent. These steels have very different strengths and uses depending on the chosen alloy. High-strength low-alloy (HSLA) steels, or microalloyed steels, are designed to provide better mechanical properties and/or greater resistance to atmospheric corrosion than conventional carbonsteels in the normal sense.
Alloy steel can further classify as
- Low alloy steels: in which sum of total Alloying elements is < 5%
- High alloy steels: in which sum of total Alloying elements is > 5%
Uses of Alloy Steel
Use of Alloy Steel is mainly in automobile industry and machinery parts. Alloy steel can be used in process area where carbon steel has limitation, below are few application of alloy steel:
- High-temperature services such as Heater tubes, Alloy Steel Boiler Tubes
- Low-temperature services such as Cryogenic application
- Very High presser service such as Steam Header
- Used in construction of aircrafts and heavy vehicles for crank shafts, camshafts and propellor shafts, etc.
- General Engg and mould basis.
