ASTM A387 Grade 21 Steel vs ASTM A514 Steel
The ASTM A387 specification is the Standard Specification for Pressure Vessel Plates, Alloy Steel, Chromium-Molybdenum intended primarily for use in welded boilers and pressure vessels designed for elevated temperature service. Gnee can supply A387 Grade 22 to the tension test requirements for Class 1 and/or Class 2.
The ASTM A514 specification is the Standard Specification for High-Yield-Strength, Quenched and Tempered Alloy Steel Plate, Suitable for Welding used in applications where Yield Strengths of ≥ 100 ksi are required for plates up to 2-1/2" thick, inclusive.
What is A514 equivalent grade?
For projects requiring EN standard materials, EN S700 or EN690 may be possible alternatives to A514, depending on project requirements. Other Q&T steel plate grades have similar properties to A514 plate and may be suitable for use high wear and stress applications.
What is the hardness of A514?
| Physical Properties | Metric | Comments |
|---|---|---|
| Density | 7.85 g/cc | |
| Mechanical Properties | Metric | Comments |
| Hardness, Brinell | 264 | |
| Hardness, Knoop | 289 | Converted from Brinell |
What is A514 steel used for?
A514 steels are used where a weldable, machinable, very high strength steel is required to save weight or meet ultimate strength requirements. It is normally used as a structural steel in building construction, cranes, or other large machines supporting high loads.
