ASME SA299 Pressure Vessel Plate

ASME SA299 Pressure Vessel Plate Factory

IBC (Tianjin) Industrial Co., Ltd manufactur & export ASME SA299 Pressure Vessel Plates for decades to all over the world. We also provide specification such as ASME or ASTM, DIN, JIS, EN, etc., including all kinds of steel grades. This specification ASME SA299 covers manganese-silicon carbon steel plates for use in welded boilers and other pressure vessels. We produce plates under this specification in two grades. The specified minimum the yield strength decreases on thicknesses over 1 in. [25 mm]. The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements; however, current practice normally limits the maximum thickness of plates furnished under this specification to 8 in. [200 mm]. Please contact us if you would like more information.

Plates produced from coil without heat treatment or with stress relief only are subject to the additional requirements of Specification A 20/A 20M, including additional testing requirements. The values stated in inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units shown in brackets. Because the values in each system are not exact equivalents, they each used independently of each other. Using values from both systems together may result in non-conformity.

Heat Treatment

ASME SA299 Gr.A plates 2 inch [50mm] and under in thickness are normally supplied in the as-rolled condition. Plates ordered normalized or stress relieved, or both.  ASME SA299 Gr.A steel plates products over 2 inch  [50mm] in thickness shall be normalized.

Additional Service

Carbon Steel with Manganese-Silicon Plate SA299 Grade A, SA299 Grade B is subject to various tests such as Chemical Composition Test, Additional Tension Test, Charpy V-Notch Impact Test, Drop Weight Test, High-Temperature Tension Test, Ultrasonic Examination, Magnetic Particle Examination and Size & Dimension Examination. The steel conforms to steel specification standard ASME SA 299/SA 299M. Another two related steel grades are A299 Grade A and A299 Grade B according to ASTM A 299/A 299M. With regards to heat treatment for steel plate less than 50 millimetres; usually pressure vessel steel plate of grade A299 Grade A and A299 Grade B rolled in the as-rolled condition.

Technical Conditions

According to ASTM A299/A299M standard, steel plate A299 Grade A and A299 Grade B shall be choose in the following technical conditions:

  • S1.Vacuum treatment;
  • S2. Product analysis;
  • S3. Simulated post weld heat treatment of mechanical test coupons;
  • S4. Additional tension test;
  • S5. Charpy V-notch impact test;
  • S6. Drop weight test, S7. High temperature tension test.


ASME SA299 steel widely used for producing pressure and boiler equipment. Plates of this standard under 50 mm thickness commonly supplied in an as-rolled condition. The grade, a manganese-silicon carbon steel plate, can also used in welded boilers and other pressure vessels. There are two varieties available: SA299 Gr.A and SA299 Gr.B. Normalizing or stress relieving, or both, requested when ordering plates with a thickness over 50 mm; otherwise, these are generally supplied in an as-rolled state.
