1.1 This specification covers several different types of chemical passivation treatments for stainless steel parts. It includes recommendations and precautions for descaling, cleaning, and passivation of stainless steel parts. It includes several alternative tests, with acceptance criteria, for confirmation of effectiveness of such treatments for stainless steel parts.
CJS237, for Sec VIII, Div. 1, Part UHA specifies acceptance criteria for materials falling under this Part. Austenitic stainless steels are such a material. You will find acceptance to be based on lateral expansion of the specimen, rather than absorbed energy. Regards, Mike . The problem with sloppy work is that the supply FAR EXCEEDS the demand

A shop needing free-machining stainless bar for beverage fittings may seek technical assistance from his stainless steel supplier. The ultimate choice of passivation will depend on the acceptance criteria imposed by the manufacturer for whom the parts or components are to be made.
Roughness measurements of stainless steel surfaces Introduction Ra value Surface roughness is a measure of the texture of a surface. It is quantified by the vertical deviations of a real surface from its ideal form. If these deviations are great, the surface is rough, if they are small, the surface is smooth. Roughness is typically considered to

Attachment 2, ASME B31.3, "Process Piping" Acceptance Criteria Page 1 of 4 1.0 ACCEPTANCE CRITERIA FOR COMPLETED WELDS 1.1 Butt Welds 1.1.1 As-welded surfaces are permitted; however, the surface of welds shall be sufficiently free from coarse ripples, grooves, overlaps, abrupt ridges, undercut, and valleys.
Joining (MJ) Subcommittee established weld criteria for prod-uct and non-product contact surfaces of orbital tube welds. Acceptance criteria for welds on tubing systems do not allow cracks, lack of fusion, incomplete penetration, porosity open to the surface, inclusions open to the surface nor undercut.
Austenitic materials are generally recognized for their lack of ductile-to-brittle transition behavior. In other words, they do not generally display a reduction in impact energy as the test temperature is reduced. By contrast, ferritic and martensitic materials-such as the carbon steels, alloy steels, and 400-series stainless steels-exhibit reduced toughness as test temperature is reduced.
The parties involved in the market have sought acceptance criteria for scratches and indentations on different types of pipes and pipe applications. More recently, the question has been raised as to how it can be ensured that pipes laid by guided drilling or pipe-bursting have not been adversely affected. 1.2 Purpose, objectives and limitations
