BoltPort primarily stocks and supply A Grade Boltings for high temperature service.

One specimen from a set of 3 may be less than 35 ft-lbf 47 J but not less than 30 ft-lbf 41J. Combining values from the two systems may result in nonconformance with the specification.

C Phosphorus and sulfur content is 0. Bolting material ordered in the annealed condition shall have a structure a5540 for machining. The minimum average of 3 specimens shall not be less than 30ft-lbf 41 J. The hardness of material in the quenched and tempered or quenched, temepred and stress-relieved condition shall be within the limits in hardness column of the mechanical properties table.

The minimum average of 3 specimens shall not be less than 25ft-lbf 34 J. These bolts need to undergo charpy v notch impact test as compulsory requirement.

ASTM A / AM – 15 Standard Specification for Alloy-Steel Bolting for Special Applications

Combining values from the two systems may result in nonconformance with the specification. Such annealed bolting material is not intended to be used without subse-quent quenching and tempering as specified in 5. Such annealed material is not intended to be used without subsequent quenching and tempering. C Phosphorus and sulfur content is 0. ASTM A Grade B23 is a high tensile alloy steel bolting grade intended for special application such as nuclear power plant installations.

Link to Active This link will always route to the current Active version of the standard. Bolting ordered in the liquid quenched and tempered condition shall be uniformly reheated froma temperature below the cooling transformation range to the proper austenitizing temperature, quenched in a liquid medium under substantially uniform conditions, and then uniformly reheated for tempering.

One specimen from a set of 3 may be less than 30 ft-lbf 41 J but not less than 25 ft-lbf 34J. One specimen from a set of 3 may be less than 30 ft-lbf 41 J but not less than 25 ft-lbf 34J.

ASTM A540 / A540M Grade B23 Class 1/2/3/4/5 Alloy Steel Bolting

The primary melting may incorporate separate degassing or refining The molten steel may be vacuum-treated prior to or during pouring of the ingot. The hardness of material a50 the annealed condition shall not be greater than HB. These bolts need to undergo charpy v notch impact test as compulsory requirement. Tensile test, hardness, and impact test shall be measured to conform to the required mechanical properties. ASTM A Grade B21 is a high tensile ast, steel bolting grade intended for special application such as nuclear power plant installations.

This specification is expressed in both inch-pound units and in SI units. This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. The hardness shall be determined on the surface of the material removal of decarburization. Several grades of steel are covered.

However, unless the order specifies the applicable” M” specification designation SI unitsthe material shall be furnished to inch-pound units.

ASTM A540 / A540M Grade B21 Class 1/2/3/4/5 Alloy Steel Bolting

Bolting ordered in the liquid quenched and tempered condition shall be uniformly reheated axtm temperature below the cooling transformation range to the proper austenitizing temperature, quenched in a liquid medium under substantially uniform conditions, and then uniformly reheated for tempering. Combining values from the two systems may result in non-conformance with the standard.

The hardness of material in the annealed condition shall not be greater than HB. C Phosphorus and sulfur content is 0. We offer Rupture Test Facility for sufficient quantity order.
