supplier ASTM A516 Boiler Plate
We have an extensive stock of ASME/ASTM A516 Boiler Plate. Our focus is in supplying very high quality plates for demanding applications in the oil and gas industry.As a result we have a large proportion of very heavy plates over 50mm,and going up to 300mm, and are able to meet significant requirements onan ex-stock basis.
Most of our high grade ASTM A516 plates have been independently tested and have an EN10204 3.dua certificate from Lloyds Register (or other globally recognised testing body). All plates have at least a tiga.1 certificate.ASME/ASTM A516 Boiler Plates Available Ex-StockA516 Grade 60 – 6 – 150 mmA516 Grade 70 – 6 – 150 mmASTM/ASME A516 Background
ASTM A516 is a specification for carbon steel plates for moderate and low temperature service. The plates are generally used for the construction of welded pressure vessels when an improvement in notch toughness is required.
ASTM A516 (or ASME SA516) is available in four grades, Gr55, Gr60, Gr65 and Gr70 with tensile strengths ranging from 380 MPa to 620 MPa depending on the grade. Oakley Steel supplies A516 Grade 60 and A516 Grade 70. We supply ASTM A516 65 as HIC resistant plate – it is triple certified as A516 60/65/70 and meets the requirements of all three grades for that purpose.
Whilst it is possible for very thick plates (200 mm) to be produced that meet the requirements of the standard the thickest generally available plates from stock are 150mm. Dillinger Hutte are world renowned for heavy plates and have produced some of the thickest A516 plates ever rolled
ASTM A516 steel plate is killed and has a fine austenitic grain size. Plates under 40 mm thick can be supplied as rolled or normalised, whereas plates over 40 mm thick are normalised.Reasons to Buy ASME/ASTM A516 Boiler Plate from Oakley Steel
Thecompanies that buy from us are normally fabricators with an ASME Ustamp or equivalent certification from the National Board, Lloyds, DNVetc. For many boilers lower quality steel is sufficient – for example inthe Palm oil industry and in food refining. However for boilers (pressure vessels, heat exchangers, columns and towers) in the oil and gas industry our boiler plates meet the very high specifications required.
Andthis is where our plates stand out against Japanese and Korean steels.The steel, and the MTC’s that support the plates, are of very highquality and this makes acceptance – both at tender and during productionand commissioning – by the EPC or oil major far easier. A couple ofexamples:
In one case a Malaysian company near Port Klang hadbought some A516 70 from us. They reported that when the Shell inspectorcame to site to do PMI (Positive Material Identification) on the vesselhe was shocked by the numbers and did a retest to check that themachine was not in error. Low critical values of Phosphorus and otherresidual elements mean great performance.
A customer in Singapore was being asked to supply a vessel for sour service with a CLR of 0%. This is an extreme requirement because it means that the test sample cut from the HIC resistant plate effectivelyhave to have no cracks in them after being bathed in acid solution for 4days. Normally HIC plates are sold with lima%, 10% or 15% CLR. Verydubious about being able to meet this requirement from stock we startedhaving a look at our MTCs and actually found the requisite 30 tonnes ofplates in stock. Wow! Whilst this is a very occasional requirement itdoes demonstrate that our boiler plate from stock often meets thetoughest requirements. Not need to wait for new rolling.A516 Steel Supplementary Requirements
The following supplementary requirements from ASTM A20 can be met by A 516:S1 – Vacuum treatmentS2 – Product AnalysisS3 – Simulated Post Weld Heat TreatmentS4.1 – Additional Tensile TestS5 – Impact Test (Charpy Notch)S6 – Dropweight TestS7 – Hot Tensile TestS8 – UT (Ultrasonic Testing) to A435S9 – Magnetic Particle ExaminationS11 – UT to A577S12 – UT yo A578S17 – Vacum Carbon Deoxidised Steel
Some of the requirements are met through the mill production process whereas others such as PWHT, Impact testing and UT examination are available as additional tests.A516 Pressure Vessel Steel Chemical Composition
Thistable provides the main features of the chemical composition ofdifferent grades A516 boiler plate steel as required by ASTM?ASMEA516/A516M. It is not complete as we have not included many of the minoruse cases. These may have a major impact in your application so pleaseuse this for reference purposes only and refer to your original and upto date copy of the relevant standardWe have listed thechemical and physical properties of the grades on the table below toallow for clear comparison. ASME SA 516 gram 70 has the highest tensileand yield strength of the three grades and this is due to the highercarbon content of the steel. The other principal alloying elements arethe same as the other two ASME SA 516 grades.
Generally the higher the grade, in this case ASME SA 516 gr 70, the higher quality steel it is considered to beand the wider the range of possible applications. Our experience isthat customers tend to choose either ASME SA 516 gram 60 or ASME SA 516 gr70, with ASME SA 516 gram 65 being less popular. This is because thesmall difference between the grades mean that many heats of A16 70 can bedual or triple certified for all three grades and the small pricedifferential means that for procurement purposes the additional cost ofprocuring ASME SA 516 gram 70 is small, Jual Pipa Schedule di Medan whilst the engineering andlogistical benefits can be significant.
Our steel plates are of high quality and if you check summary the sample Mill Test Certificate on the test certs laman you can see that the standard requirements are comfortably exceeded.
ASME and ASTM Standards are harmonised so ASME SA 516 gram 70 is exactly the same as ASTM A 516 gram 70. On some specifications this is written as ASTM/ASME A/SA 516 gr70 or a similar combination of the same meaning.ASTM A516 Mechanical Properties:A516 Grade 60A 516 Grade 65A516 Grade 70Tensile Strength (ksi)60-8065-8570-90Tensile Strength (MPa)415-550450-585485-620Yield Strength (ksi)323538Yield Strength (MPa)220240260Elongation in 200mm (%)211917Elongation in 50mm (%)252321Max Thickness (mm)205205205
