As per the specification SA 516 Grade 60/70 Hardness values are not specified. For welded coupons, the values are normally specified in the buyers specifications. In most of the cases it is specified 250 as a maximum value (specified by the end users specification data). You may check up with your clients specifications for the requirements. We will send Stress Relieving Chart with all reports, if requested.
