With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
To see how these methods can vary we determined the necessary preheat for making a fillet weld on two 1.75-inch thick ASTM A572 Gr 50 plates. Results: Manufacturers recommendation: Arcelor Mittal states that for their ASTM A572 Grade 50 (BethStar 50) no preheat is necessary when the steels initial temperature is 0F or above.
A572 Grade 50 has a 139% greater Yield Strength than A36 steel. A572 steel does not require preheat or post heating during the welding process and standard AWS D1.1 welding standards apply. Higher grades of steels will require preheating which is not economical compared to savings in weight.
Yes you are reading it right.The preheat temperature has to be 150 degrees 3" (I think that is what it is)in all directions from where the weld is.Seems like alot of heat but it is the same way if you have a 3/8 plate going onto a 1"3/4 plate .It is sad but true.

Certain joint designs may allow you to undermatch the filler metals strength to the lower-strength material. For instance, some fillet joints created by joining a 100-KSI yield, quench-and-tempered material like A514 to an even higher-strength, proprietary high-strength, low-alloy 130 material can accommodate welds with 70-KSI filler metals.
Leeco Steel distributes A572 steel plate is used in a variety of structural applications including bridges, buildings, construction equipment, and more. We distribute A572 steel plate in the following grades: Grade 42, Grade 50, Grade, 55, Grade 60, and Grade 65.

Tolerance under specified thickness .010". A 3/4 x 52" wide plate, for example, would have a tolerance range of .740/.780" Because of tolerances, i.e. thickness, flatness and camber, as well as the hot roll condition, ASTM A572 Grade 50 generally does not finish to specified thickness.

Table 8-4 summarizes these results as well as data provided by a single producer for ASTM A913 material. Table 8-3 - Typical Tensile Requirements for Structural Shapes ASTM
An example here would be welding ASTM A572 Grade 50 to AISI/SAE 4140, in which the former material has both chemistry and mechanical requirements, but the latter has only a chemistry requirement. It is important to determine the weldabilty of dissimilar strength materials prior to joining them together for a number of reasons.
The most common grade of A573 Chapel Steel stocks is Grade 50. A572 is a high strength low alloy steel plate used in a variety of structural applications. The most common grade Chapel Steel stocks is Grade 50.
Both ASTM A36 carbon steel and ASTM A572 grade 50 are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 99% of their average alloy composition in common. For each property being compared, the top bar is ASTM A36 carbon steel and the bottom bar is ASTM A572 grade 50.

BethStar steel plate delivers a lower applied cost than carbon steel The BethStar family of low-carbon, control-rolled, high-strength steel plate offers improved toughness, weldability and formability when compared to competitive grades, such as ASTM A572. Four grades - BethStar 50, 60, 70 and 80 - enable design engineers
two grades (ASTM A36 and ASTM A572 Grade 50) of structural steels, based on mill test reports from selected domestic producers for the 1992 production year. Data were also collected for "Dual Grade" material that was certified by the producers as complying with both ASTM A36 and ASTM A572 Grade 50.

ASTM A572 STEEL (GRADE 50) INX-EXTEN is available with. 50,000 psi min strength level. It is moderately priced and offers high strength in combination with good formability and weldability. Atmospheric corrosion resistance is about equal to plain carbon steel. Conform to SAE J41 0 and Grade 950X. STEEL PLATE COILS
Applications include: truck frames, crane booms, and rail car components. Made to Grades 50, 60, 70 and 80 the grade designating the yield strength. Chapel Steel stocks in Grade 80 up to 3/4 , Grade 70 over 3/4 to 1 and Grade 60 over 1 to 1-1/2.
A612, A588 Grade A, A572 Grade 50, A663 Grade C, and A633 Grade E show: 1. Base metal strength and notch toughness are generally degraded by long PWHT. 2. HAZ and Weld Metal toughness are affected by welding parameters. 3. HAZ sometimes benefit from PWHT and sometimes degraded. 16
