Thickness 1.0-2.0mm Astm A 36 Steel Plate Full Hard ISO9001

Thickness 1.0-2.0mm steel plate Full Hard

ASTM A 36 steel is a widely accepted general purpose structural quality steel offering a constant 36 ksi min. yield point for all thicknesses of material. It is widely used in the construction of buildings, bridges and other structures by means of welding, bolting or riveting. This steel is useful because of its wide availability.

ASTM A 283

ASTM A 283 covers low and intermediate tensile strength carbon steel plates for general manufacturing and constructional applications.This material is normally supplied in the rimmed or semikilled types of steel and is particularly suitable for the economical production of assemblies requiring a considerable amount of forming. Variations in low temperature impact properties are great and these steels are not recommended for those applications requiring low temperature notch toughness.

ASTM A 285

Specification for Low and Intermediate

Tensile Strength Carbon Steel Plates for Pressure Vessels

ASTM A 285 covers three grades of low and intermediate tensile strength carbon steel plates intended for fusion-welded pressure vessels up to a maximum of 2″ thick. This material is normally supplied in the rimmed or semi-killed types and is particularly suitable for economic production for low-pressure vessels coming under the jurisdiction of the ASME Pressure Vessel Code.

ASTM A 242

Specification for High Strength Low Alloy Structural SteelsASTM A 242 covers high strength low alloy steel shapes, plates and bars for welded, riveted or bolted construction intended primarily for use as structural members where saving in weight or added durability are important.

ASTM A 515

Specification for Carbon Steel Plates for Pressure Vessels for Intermediate and Higher Temperature ServicASTM A 515 covers steel plates of intermediate tensile strength for pressure vessels to be operated at intermediate or higher temperatures. The four grades offer excellent combinations of strength, weldability and toughness to permit designers flexibility in the design of pressure vessels coming under the jurisdiction of the ASME Pressure Vessel Code.

ASTM A 516

Specification for Carbon Steel Plates for Pressure Vessels for Moderate and Lower Temperature Service

ASTM A 516 covers steel plates of intermediate tensile strength for pressure vessels to be operated at atmospheric or lowertemperatures. The four grades offer excellent combinations of strength, weldability and toughness to permit designers flexibility in the design of pressure vessels coming under the jurisdiction of the ASME Pressure Vessel Code.

CSA G40.21

STRUCTURAL QUALITY STEELS

In this format, the standard clearly identifies the types of steel that should be considered whenever resistance to brittle fracture is a design consideration; Type WT, AT or QT. These designations also alert the steel producer to the fact that the intended application requires a steel that is capable of displaying a specific level of notch toughness.
To further simplify and expedite the ordering of Type WT, AT or QT steel and to eliminate possible confusion between the designer and the producer, one of five categories of notch toughness must be selected and specified. For every grade covered by these types, each category represents a specific level of absorbed energy at a particular temperature as indicated in Tables 2 & 3.For example, if designers require a 50 Ksi minimum yield weathering steel with certified impact testing of 20 ft. lbs. at 0°F, they simply specify 50 AT, Category 2. Thus there can be no confusion at the steel producer, or at any step between the designer and the steel mill about the exact product required.
With these changes, the design community has been provided with a logical, comprehensive range of structural steels that reflects the requirements of today’s designs and applications.

TYPE W – WELDABLE STEEL

Steels of this type meet specified strength requirements and are suitable for general welded construction where notch toughness at low temperatures is not a design requirement. Applications may include buildings, compression members of bridges, etc.

TYPE WT – WELDABLE NOTCH-TOUGH STEEL

Steels of this type meet specified strength and Charpy V-Notch impact requirements and are suitable for welded construction where notch toughness at low temperature is a design requirement. The purchaser, in addition to specifying the grade, must specify the required category of steel that establishes the Charpy V-Notch test temperature and energy level. Applications may include primary tension members in bridges and similar elements.

TYPE R – ATMOSPHERIC CORROSION-RESISTANT STEEL

Steels of this type meet specified strength requirements. The atmospheric corrosion resistance of these steels in most environments is substantially better than that of carbon structural steels with or without a copper addition.* When properly exposed to the atmosphere, these steels can be used bare (unpainted) for many applications. These steels may be welded readily up to the maximum thickness covered by this Standard. Applications include unpainted siding, unpainted light structural members, etc, where notch toughness at low temperature is not a design requirement.

TYPE A – ATMOSPHERIC CORROSION-RESISTANT WELDABLE STEEL

Steels of this type meet specified strength requirements. The atmospheric corrosion resistance of these steels in most environments is substantially better than that of carbon structural steels with or without a copper addition.*When properly exposed to the atmosphere, these steels can be used bare (unpainted) for many applications. These steels are suitable for welded construction where notch toughness at low temperature is not a design requirement
and are often used unpainted. Applications are similar to those for Type W.

TYPE AT – ATMOSPHERIC CORROSION-RESISTANT WELDABLE NOTCH-TOUGH STEEL

Steels of this type meet specified strength and Charpy V-Notch impact requirements. The atmospheric corrosion resistance of these steels in most environments is substantially better than thatof carbon structural steels with or without a copper addition.* When properly exposed to the atmosphere, these steels can be used bare (unpainted) for many applications. These steels are suitable for welded construction where notch toughness at low temperature is a design requirement. The purchaser, in addition to specifying the grade, must specify the required category of steel that establishes the Charpy V-Notch test temperature and energy level. Applications may include primary tension members in bridges and similar elements.
