With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
dear frnds, m doing project on welding of ASTM A516 garde 70 or SA 516 grade 70. for this m doing smaw and co2 welding and then its mechanical testing and micro examination and finally cost comparison. so if any one is having the microstructures of A516 weldment and HAZ, plz mail me bcos whatever i ve got is not gud.

RE: Welding of A-36 and A516 Gr 70 GenB (Mechanical) 30 Jun 13 03:08 Nothing is wrong with A36 material plate used as shell or heads it was a good choice in the pass, better materials came along and now A36 is not used as press.part The preferred A516 happens to be near the cost of A36 and with greater advantage.

ASTM A515 STEEL (GRADE 70) has greater strength than A285 and intended for intermediate and high temperature boilers and pressure vessels. It is a silicon killed, coarse grained steel that requires careful welding techniques. ASTM A516 STEEL (GRADE 70) is similar to A515 but is intended for lower temperature applications. It is also silicon killed, but has a finer grain and improved notched toughness.
Welding alloy steels often may require unique weld or heat treat considerations. Compare the low alloy steels chemistry and mechanicals with a standard A36 steel. Remember this site is only a guide, weld responsibility starts with "you" First verify the weld consumable and then the material heat treat recommendations.
Dear All, Can we used E7018 electrode for SA516 Gr.70 material (Impact Tested at -46 oC) or we need to use other?? Kindly clarify. Regards, Vijay,
Re: [MW:11782] Welding of SA 516 Gr.70 I do not have specific technical reason on why you use SMAW with E7018 and then back grinding? Is there any technical requirement from Client?
The SA516-70 has a minimum specified tensile strength of 70-90ksi. The E101T1 is overmatching this. When welding 4140 to a lower tensile strength steel it does not add any strength to the connection to match the higher strength metal (in cjps).
Grade 70 (as rolled) blue and brown; Grade 70 (normalized) blue and silver. ASTM A516 (ASMESA 516) Intended for low temperatures where improved notch toughness isrequired. ASTM A516 has fine grain structure and is silicon killed. Grade 70,stocked in the as rolled or normalized condition.
Methodology alterations in the nature of precipitates distribution due to The investigation was performed on 6.8 mm thick of the welding process, the surface of each unetched FW joints ASTM A516 grade 70 carbon steel FW joint using MMA, were analyzed using Energy Dispersive X-ray (EDX) which MIG and TIG welding operations.
and Excalibur 7018-1, are preferred over Jetweld LH-70 for most pipe and out-of-position welding. Jetweld LH-3800 can be used in place of E7018s for flat and horizontal fillet, lap, and flat butt welds. (2) Almost any E60XX or E70XX electrodes can be used. First, select electrode based on the joint requirements. If code,

SPECIFICATION FOR PRESSURE VESSEL PLATES, CARBON STEEL, FOR MODERATE- AND LOWER-TEMPERATURE SERVICE SA-516/SA-516M (Identical with ASTM Speci cation A 516/A 516M-06) 1. Scope 1.1 This speci cation covers carbon steel plates intended primarily for service in welded pressure vessels where improved notch toughness is important.
For example, when welding A514a minimum 110-KSI tensile, low-alloy, quench-and-tempered steelto A36 steel with a minimum 58-KSI tensile strength, choose a filler that more closely matches the A36 base metal, such as a filler metal with 70-KSI tensile, the lowest strength typically available on the market.
For example sa 516 grade 70 has the highest tensile and yield strength range due to the highest Carbon content(up to0.28%). For higher grade like sa516 gr-70 steel plate, preheating might be needed for metal arc welding process, especialy with thick steel plate.

secon is weldability for servicethat is, the ease with which required serv ice properties are obtained. In both cases, weldability is a function of the steel being joined, the application, the location and design of the weld joint, the welding process, and the welding procedure. Thus, weldability is not an intrinsic property of a metal.
