There are two classes available according to tensile strength levels:Class 1 and Class 2. The ASME SA-387/ ASTM A387 Gr.11 steel has the nominal composition of 1.25Cr-0.5Mo-Si with UNS designation number of K11789 and P number of 4. Manufacture & Heat Treatment The ASME SA-387/ ASTM A387 Gr.11 plates shall be made by a killed process. ASTM A387 / A387M - 17a Standard Specification for ASTM A387 / A387M - 17a Standard Specification for Pressure Vessel Plates, Alloy Steel, Chromium-Molybdenum. 1.4 The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements.
Due to low weight, it makes any fabrication application lightweight and convenient. ASTM / ASME A /SA 387 Grade 22 / F22 Plates have great machinability, formability, and fabricability that is ideal for fabrication industries. These have many embedded features which make the machining of ASTM A387 Grade 11 (K11789) 1.25Cr-0.5Mo Steel May 30, 2020 · Among alloy steels, the composition of ASTM A387 grade 11 steel is notable for containing a comparatively high amount of chromium (Cr). Chromium is used to improve corrosion resistance and most mechanical properties (particularly at higher temperatures). All values are % weight. Ranges represent what is permitted under applicable standards. ASTM A387 Grade 11 Alloy Steel Plate and SA 387 gr 11 astm a387 grade 11 comes under steel specification of ASTM A387/A387M. astm a387 grade 11 plate is an alloy steel which can be supplied in normalised and tempered condition. a387 gr 11 platehas the ability to be fully resistance tocrevice corrosion, pitting, and stress corrosion cracking resistance.
ASTM A387 Grade 11 Cl.2 P, No 4, Gr-1 material plate is an Alloy Steel and supplied in Normalized and Tempered condition. Typical UTS range for this steel is (75 to 100 KSi or 515 to 690 Mpa). A387 Grade 11 welding can be done using low carbon welding electrodes E7018-B2L or E71T1-B2L. ASTM A387 Grade 22 Class 2 Chromium Molybdenum Dec 16, 2016 · A387 Grade 22 Class 2 is a grade of chromium-molybdenum alloy intended primarily for use fabricators in welded boilers and pressure vessels which are designed for use in raised temperature service. With excellent heat resistance and anti corrosive/oxidation qualities, this steel grade is ideal for use in the chemical, oil and gas industry. ASTM A387 Grade 22 Class 2 Steel ::MakeItFromMay 30, 2020 · ASTM A387 grade 22 class 2 is ASTM A387 grade 22 steel in the normalized and tempered condition. The graph bars on the material properties cards below compare ASTM A387 grade 22 class 2 to:wrought alloy steels in the same category (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in
ASTM A387 steel specification refers to 6 grades levels of alloy steel plate for elevated temperature applications, classified by chromium and molybdenum content, Grade 11 and Grade 12 has similar chemical content,they can be used in welded pressure vessels and industrial boilers, and mostly in oil gas and petrochemical industry, generally it is used for transportion of medium at high temperature. ASTM/ASME A387 Grade 22 Class 2 - Oakley SteelA387 Grade 22 Class 2 is a standard chrome moly steel plate according to ASME/ASTM standard A387/A387M. It is used in a wide variety of applications where the boiler, heat exchanger or pressure vessel will be at high temperatures. A387 Grade 22 plates come in thicknesses of between 8 and 40mm and in standard plates sizes of 2m x 12m and 3m x 12m Chrome Moly Steel Plate to ASTM A387 and EN10028-3Chrome Moly Steel Plate to ASTM A387 and EN10028-3. 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.
