LOW CARBON PLATE STEEL
Low Carbon Plate Steel is manufactured to three separate carbon ranges that relate to thickness and end-use requirements. Plates 3/4″ and lighter are produced to the lowest carbon range (0.10-0.20) for maximum cold forming and welding properties. Sizes 3/4″-1 1/2″ the carbon range is (0.15-0.25) which gives improved machining while retaining its forming and welding properties.
Plates over 1 1/2″ have carbon increasing to (0.20-0.33), this is a killed steel that provides the best combination of strength, weld ability, and structural soundness.
MEDIUM CARBON PLATE STEEL
Medium Carbon Plate Steel in the (.40-.50) carbon range is silicon killed and higher carbon for improved strength. Light and medium thicknesses can also be heat treated for greater strength. Machinability is good, but forming and welding properties are limited.
STRUCTURAL QUALITY STEEL
Abrasion-resistant steel is produced to a special carbon-manganese specification, developed specifically for applications requiring superior wear resistance, and will usually outlast ordinary steel grades by a wide margin.
AR360 STEEL is a medium strength and hardness; quenched and tempered plate, of modest price, and excellent wear properties.
AR400 STEEL is a high hardness; high strength quenched and tempered chrome-moly, boron treated alloy plate with good resistance to atmospheric corrosion and impact abrasion.
ABRASION RESISTANT STEEL GRADES
Abrasion-resistant steel is produced to a special carbon-manganese specification, developed specifically for applications requiring superior wear resistance, and will usually outlast ordinary steel grades by a wide margin.
AR360 STEEL is a medium strength and hardness; quenched and tempered plate, of modest price, and excellent wear properties.
AR400 STEEL is a high hardness; high strength quenched and tempered chrome-moly, boron treated alloy plate with good resistance to atmospheric corrosion and impact abrasion.
PRESSURE VESSEL QUALITY STEEL
Pressure Vessel Quality steel plate is produced to tightly controlled ASTM standards in order to provide superior grade of carbon steel plate designed specifically for pressure vessel and boiler applications but also suited to a variety of less demanding commercial applications.
PVQ plate is subject to a specified series of tests to ensure conformance to standards.
ASTM A285 STEEL (GRADE C) in fire box and flange quality designed for fusion welded boilers and pressure vessels where moderate strength and good forming is required.
ASTM A515 STEEL (GRADE 70) has greater strength than A285 and intended for intermediate and high-temperature boilers and pressure vessels. It is a silicon killed, coarse grained steel that requires careful welding techniques
ASTM A516 STEEL (GRADE 70) is similar to A515 but is intended for lower temperature applications. It is also silicon killed, but has a finer grain and improved notched toughness. Stocked in an as rolled condition and Chirpy tested.ASTM A572 STEEL (GRADE 50) INX-EXTEN is available with. 50,000 psi min. strength level. It is moderately priced and offers high strength in combination with good formability and weld ability. Atmospheric corrosion resistance is about equal to plain carbon steel. Conform to SAE J41 0 and Grade 950X.
