ASTM B443 Standards And Specifications

ASTM B443 is the standard specification for Inconel 625 Sheet, Plate and Strip, having UNS N06625.

ASTM B443 Sheet Plate

ASTM B443 Plate

ASTM B443 is a standard specification Inconel Alloy Sheet or Plate. Alloy UNS N06625 products are furnished in two grades of different heat-treated conditions: Grade 1 (Annealed)--Material is normally employed in service temperatures up to 1100oF (593oC). Grade 2(Solution Annealed)--Material is normally employed in service temperatures above 1100oF (593oC) when resistance to creep and rupture is required. Nickel based alloys are very useful materials for the manufacture of high quality sheet plate. One of the key reasons is that they offer excellent corrosion resistance in both aqueous and high temperature applications. Inconel 625 having excellent mechanical properties at both extremely low and extremely high temperatures also having high resistance to oxidation at elevated temperatures up to 1050C.

Inconel 625 Sheet Plate

Inconel 625 Sheet Plate is a nickel-chromium alloy bar that contains supplemental amounts of columbium, iron, molybdenum, aluminum, and titanium. Inconel 625 Sheet Plate have high strength properties, heat treatable, good corrosion resistance, formability and weldability. Inconel 625 Sheet Plate is commonly used for valves, fasteners, tubing materials and mandrels. Inconel 625 Sheet Plate has excellent cryogenic and heat ranges. Common uses of Inconel Alloy 625 include deployment in gas turbines, subservice safety valves, aircraft engines, thrust reversers, and industrial fasteners.

ASTM B443 covers precipitation hardening bolting material (UNS N06625) and bolting components for high temperature service. Inconel 625, AMS 5596 AMS 5662 ASTM B443, UNS N06625 High Temperature (UNS N06625), Ni 52.5, Cr 19.0 Fe 18.5 Mo 3.0 Nb+Ta 3.6

Scope And Manufacturing

ASTM B443 materials shall be sampled, prepared, and tested accordingly to examine their conformance to dimensional (thickness, weight, width, diameter, length, straightness, edges, squareness, and flatness), mechanical (tensile and yield strengths, and elongation), and chemical composition requirements. The sheet process of cold rolling occurs with the metal below its recrystallization temperature (usually at room temperature), which increases the strength via strain hardening up to 20%. It also improves the surface finish and holds tighter tolerances. Common cold-rolled products include sheets, strips, bars, and rods; these products are usually smaller than the same products that are hot rolled. Because of the smaller size of the workpieces and their greater strength, as compared to hot rolled stock, four-high or cluster mills are used. Cold rolling cannot reduce the thickness of a workpiece as much as hot rolling in a single pass.
