Alloy Steel Plates and Sheets that are made with preeminent quality carbon and compound steel. Accessible in various evaluations and designs, the plates produced by us hold high elasticity and have longer administration life.
We stock one of the most extensive ranges of Chrome Moly steel plate in Europe both to ASTM/ASME and EN10028-2. It is all available ex-stock for immediate delivery or shipping to your production facility. Chromium molybdenum plates fill an important gap between aluminium and stainless steel.
We don’t stock or offer grades 21, 9 or 91 The chemical and physical properties of A387 allow it to resist high pressures at high temperatures making it an ideal material for boilers and process and pressure vessels in the oil and gas industries.
All Chrome Moly steel plates are killed and thermally treated as required by ASTM A387 which also specifies minimum and maximum quantities of the following elements in the steel: chemical requirements for carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, nickel, vanadium, columbium, boron, nitrogen, aluminum, titanium, and zirconium. A387 plate has to undergo product, chemical and tensile testing (which is documented in the MTC or material test certificate) – with specific requirements that have to be met for tensile strength, yield strength, and elongation.

USES AND APPLICATIONS OF CHROME MOLY STEEL PLATE
Chrome Moly steel plate is popular in the oil and gas industry for on and offshore production facilities because of the alloy’s key properties. It is also used extensively in the energy industry as a key component in power plants. It can be found in:
boilers and pressure vessels,
Heat exchangers
Flanges, fittings and valves
ducting and pipe supports
CHROME MOLY STEEL PLATE: HIGH TENSILE STRENGTH AT HIGH TEMPERATURES:
A387 Chrome Moly steel plate has a much higher heat resistance than other carbon steels and it is thus exceptionally useful for applications where hot fluids or gases are being processed at high temperatures. The chromium and the molybdenum are the key alloying elements. They provide many of the properties of stainless steel at a reduced costs. (typically A387 alloy steel has 0.5% t0 5% Chromium content as opposed to 16% in stainless steel).
ASTM A387 Grade 12 Class 2, 1% chromium – 1/2% Molybdenum – Effective working temperature up to 560°C
ASTM A387 Grade 11 Class 2, 1.25% chromium – 1/2% Molybdenum – Effective working temperature up to 575°C
ASTM A387 Grade 22 Class 2, 2.25% chromium – 1% Molybdenum – Effective working temperature up to 600°C
EXCELLENT CORROSION AND OXIDATION RESISTANCE OF CHROME MOLY STEEL PLATE
The Molybdenum component in the SA387 alloy, as well as increasing the tensile strength at high temperatures, also provides high resistance against oxidation and corrosion by increasing the lattice strain of the steel structure. This effectively stops the corrosive agents from dissolving the iron out of the steel structure. This makes it effective in applications where salt water is present such as desalination plants, purification plants, offshore applications and users of large quantities of brine.
