This specification covers molybdenum alloy steel plates, intended particularly for welded boilers and other pressure vessels. Plates under this specification are available in three grades having different strength levels: Grade A; Grade B; and Grade C. The steel shall be killed. The steel shall conform to the chemical requirements specified. Tension tests on plates shall conform to the requirements specified. Plates under this specification are available in three grades having different strength levels as follows:
This specification covers carbon steel plates intended primarily for service in welded pressure vessels where improved notch toughness is important. According to different strength levels, the plates are available in four grades: Grades 55, 60, 65, and 70. The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements. The steel shall be killed and shall conform to fine austenitic grain size requirements. The mechanical properties such as tensile strength, yield strength, and elongation shall be determined by a tension test for the plates.

Steel samples shall also undergo the tensile test and conform to required values of tensile strength, yield point, and elongation.
WEAR RESITANT STEEL PATES is used in areas where there is likely to be a high degree of abrasion or wear of the steel plate. Steels with a high HB rating (Brinel Hardness) are intended for applications where wear or abrasion resistance is important. The benefit of using an abrasion resistant steel is that that the plant, machinery or constructions working life can be extended considerably. This can significantly improve the reliability, durability and safety of structures and equipment. It also helps to reduce the maintenance costs associated with wear and breakdown of plant. 400 HB steel is over 3 times harder than mild steel (120HB), but only a third as hard as stainless steel (1250HB). Abrasion & mechanical wear-resistant steel plates for quarries & construction machinery: gravel & stone conveying plants (routes, chutes, hoppers) & crushing plants. Shovels, diggers, graders, bulldozers, dumpers, dredging machines, crushers, grinders, screens, hoppers, mixers, moulds for concrete aggregates. Wear resistance plates for mining machinery. Extractors, unloaders, spiral chutes, crushers, grinders, screens, conveyors. Abrasion-resistant steel plates for Cement Plants & Refractory Product Plants: hoppers, crushers, chutes, cyclones, excavator buckets

Nearly 3 times as strong as A36. Used as liners for construction equipment, mining machinery, chutes, wear plates, etc.
Stainless Steel, Duplex Steel, High Nickel Alloys & Titanium Plates
Stainless steel is used primarily when corrosion or oxidation is a problem. The function that they perform cannot be duplicated by other materials for their cost. Over 50 years ago, it was discovered that a minimum of 12% chromium would impart corrosion and oxidation resistance to steel. Hence the definition “Stainless Steels”, are those ferrous alloys that contain a minimum of 12% chromium for corrosion resistance. This development was the start of a family of alloys which has enabled the advancement and growth of chemical processing and power generating systems upon which our technological society is based. Subsequently several important sub-categories of stainless steels have been developed. The sub-categories are austenitic, martens tic, ferritic, duplex, precipitation hardening and super alloys.
Duplex /Super Duplex Steel Width : 1250/1500/2000
Duplex & Super Duplex
S32750,
S32760
SAF 2205,
SAF 2507
A category of stainless steel with high amounts of chromium and moderate nickel content. The duplex class is so named because it is a mixture of austenitic (chromium-nickel stainless class) and ferritic (plain chromium stainless category) structures. This combination was originated to offer more strength than either of those stainless steels. Duplex stainless steels provide high resistance to stress corrosion cracking (formation of cracks caused by a combination of corrosion and stress) and are suitable for heat exchangers, desalination plants, and marine applications
