TECHNICAL SPECIFICATION SHEET ER90S-B3 CR-MO …90S-B3 is used to weld such alloys as 2 1/4% Cr-1% Mo steels, which are found in high temperature and high pressure piping and vessels. May also be used on carbon steels to Cr-Mo steels but should always have careful control of preheat, inter-pass and post-heat to avoid cracking. Use with a pre-heat and inter-pass temperature of 375°f minimum.File Size: 55KBPage Count: 2

What is the specification of steel?

This specification covers pressure vessel plates, alloy steel, quenched-and-tempered, chromium-molybdenum, and chromium-molybdenum-vanadium. As a steel making practice, the steel shall be killed and shall conform to specified fine austenitic grain size requirements.See all results for this questionWhat is the most common grade of stainless steel?Also referred to as "A1" in accordance with ISO 3506. Type 304the most common grade; the classic 18/8 stainless steel. Type 304Lsame as the 304 grade but lower carbon content to increase weldability.Reference: li.mit.edu/stuff/pm/sae-steel-grades.pdfSee all results for this questionWhat is the importance of Mo in steel?For example, Mo gives the steel higher working temperatures and added strength. Moreover, the Cr results in exceptional oxidation, and helps the steel resist corrosion in a more effective manner [1]. The Cr also provides good hardness penetration, and the Mo content guarantees the hardness is uniform [3].See all results for this question

What are some examples of ferritic steel?

These elements lower the solubility of carbonin austenite, causing increase of amount of carbides in the steel. The following elements have ferrite stabilizing effect: chromium (Cr), tungsten (W), Molybdenum (Mo), vanadium (V), aluminum (Al) and silicon (Si). Examples of ferritic steels:transformer sheets steel (3%Si), F-Cr alloys.See all results for this questionTECHNICAL SPECIFICATION SHEET ER90S-B3 CR-MO 90S-B3 is used to weld such alloys as 2 1/4% Cr-1% Mo steels, which are found in high temperature and high pressure piping and vessels.

The transition to brittle fracture has shifted to +25°C for the Cr-steel, while it remained at -50°C for the Cr-Mo steel. The slow cooling rate has not embrittled the molybdenum containing steel, it is, therefore, less susceptible to temper embrittlement.
