DETAILED INFORMATION

 Introduction to Grade:

In different evaluations of steel and its alloys, carbon steel ASTM SA105 forged fittings are produced. We fabricate Forged Pipe Fittings with the highest accuracy, ensuring our products meet universal quality parameters. Carbon Steel Fittings are generally designed for sturdiness, erosion resistance, and dimension accuracy.

ASTM A105 Grade Pipe & Tubes have several advantages, such as their strength, dimensional accuracy, and high durability, regarding raw material quality at the national and international levels.

 Systems can only succeed or crack if proper precautions are taken during their construction. For several reasons, components like the astm a105 carbon steel threaded bar need to follow specifications in pressure systems. As a first step, these components are designed to connect systems produced by manufacturers using regulated specifications, such as ASTM A105.

To ensure proper fit in these systems, ASME SA105 Carbon Steel Square Bar must follow the specification down to the minute details. The pressure applied to systems can vary from a low correct rate to a high within a few minutes. Selecting the suitable material to produce an astm a105 round bar is crucial if longevity is the buyer’s objective.

As specified in the specification, heat treatments such as annealing, normalizing, tempering, or quenching improve the performance of the ASTM A105 carbon steel rod at both ambient and high temperatures, while also providing strength so that the alloy can maintain its properties at these temperatures. Carbon A105 Cold Drawn Bar must meet mechanical property requirements such as tensile and yield strength, area reduction, elongation, and hardness.

The hardness is:

From 137 to 187.

 Treatment with heat:

Except for ASTM SA 105 carbon steel forgings, no heat treatment is required. There are, however, some exceptions that will require heat treatment to improve their mechanical properties.

Forgings made from A105 carbon steel typically undergo annealing (A), normalizing (A), normalizing and tempering (NT), and quenching and tempering (QT). Many clients require normalizing at approximately 950°C for 2.5 hours to eliminate possible internal stresses in the forgings. The materials are usually marked with “ASTM SA105N”.

The hardening process:

Oil quench temperature of 850°C to 870°C

 Temptation:

The temperature ranges from 425°C to 870°C depending on the properties

 Forging Properties:

Start at 1150°C and finish at 925°C.

 ASTM  SA105 carbon steel can be forged at 2200 to 1700 F, followed by quenching, tempering, or normalizing. A number of factors, such as the complexity of the forged part, will determine the hot forging temperatures in the closed die forging process.

 It is only possible to check the proper forging temperature at the beginning of forging, as higher temperatures will probably lead to surface defects, such as mill scales, which will result in uneven surfaces. A lower temperature will not be conducive to the plastic deformation of C1045 carbon steel forged parts.

 The maximum weight of SA105 forgings is 4540 kg [10000 lb]. Welding repair of defects in ASTM SA105 flanges and fittings is absolutely prohibited by Metals-Piping (despite the standard permitting it). 

 Relieving stress:

Tempering temperature of 50°C

 Normatively:

A water quench at 830°C to 850°C

 The annealing process:

It is possible to anneal forged parts by first cooling them below 1000 F, then reheating them between 1550 and 1700 F, followed by slow furnace cooling.

The surface temperature of 800°C to 830°C

 A cool air temperature of 870/915°C

 Amount of density:

0.2844

 Mechanics:

Low alloy steels are machinable.

 The welding process:

This specification covers weldable steel.

Applicability of ASTM A105/ ASME SA-105 to ASME BPVC

Forgings made from ASTM A105 or ASME SA-105 materials, either forged flange or forged fittings, can be applied to the ASME Boiler and Pressure Vessel Codes (BPVC). The ASTM A105/ ASME SA-105 carbon steel forgings are designated with an UNS number K03504. It has a P-number of 1 and Group number of 2. It has an accurate equivalent ASME SA-181 (ASTM A181) Class 70, which can be used identically with SA-105 in any conditions of the Codes. According to Section II, Volume 1 of the Code, ASME SA-105/ SA-105M is identical with ASTM A105/ A105M.
