Re: [MW:35043] Material

By Materials & Welding

Dear Saleem,

When planning to perform a Procedure Qualification Record (PQR) and develop a Welding Procedure Specification (WPS) using the E11018M electrode, it's essential to select an appropriate base material. The E11018M electrode is a low-hydrogen, iron-powder type electrode that is designed for welding high-strength steels.

Characteristics of E11018M:

  • Classification: The "E" denotes an electrode, "110" indicates a tensile strength of approximately 110 ksi (110,000 psi), "18" specifies that it is a low-hydrogen electrode with iron powder, and "M" signifies it is designed for military or high-strength applications.
  • Applications: This electrode is commonly used for welding high-strength, low-alloy steels in applications that require high mechanical properties such as military and aerospace components, as well as in heavy equipment, pressure vessels, and structural applications.

Suggested Base Materials:

For the E11018M electrode, you should choose materials that are compatible with the high-strength, low-alloy properties of the electrode. Here are some suggestions:

  1. ASTM A514 (T-1) Steel:

    • High-yield strength and excellent weldability.
    • Commonly used in structural applications requiring high strength and toughness.

  2. ASTM A517 Steel:

    • Used in pressure vessels and boilers.
    • Offers high strength and good weldability.

  3. ASTM A710 Steel:

    • High-strength, low-alloy steel plate.
    • Suitable for applications requiring enhanced mechanical properties.

  4. ASTM A709 Grade 100/100W:

    • Structural steel for bridges.
    • High yield strength and good weldability.

  5. ASTM A572 Grade 100:

    • High-strength, low-alloy steel.
    • Used in structural applications.

  6. HY-80, HY-100:

    • High-strength low-alloy steels used in naval applications.
    • Offers high toughness and good weldability.

Selecting the Material:

When selecting the material, consider the specific requirements of your application, such as strength, toughness, and environmental conditions. Ensure that the material's mechanical properties are compatible with the E11018M electrode's characteristics.

Summary:

For welding with the E11018M electrode, you should use high-strength, low-alloy steels such as ASTM A514, ASTM A517, ASTM A710, ASTM A709 Grade 100/100W, ASTM A572 Grade 100, or HY-80/HY-100. These materials will allow you to leverage the high tensile strength and low hydrogen properties of the E11018M electrode effectively in your PQR and WPS.

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...

The Schaeffler and Delong diagrams for predicting ferrite levels in austenitic stainless steel welds

By Materials & Welding
Introduction Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steels. 'Constitution diagrams' are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. The Schaeffler and Delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds. Nickel and chromium equivalents A 'nickel equivalent' is calculated for the austenite stabilising elements and a 'chromium equivalent' ferrite stabilising elements. These are used as the axes for the diagrams, which show the compositional equivalent areas where the phases austenite, ferrite, martensite (and mixtures of these) should be present. Although intended to show the phase balance of weld fillers, these diagrams can also be used to illustrate the phase balance of the 'parent' material. There are different diagrams for dif...
