H9 = +0 / -0.062. J = Tolerance Divided e.g. 45mm dia. J9 = +/- 0.031. K = All Plus Tolerance e.g. 45mm dia. K9 = +0.062/ -0 ( The K tolerance is usually only applied to larger diameter bars - over 75mm H8 = Precision Ground. H9 = Bright Drawn. H10 = Smooth Turned In the following table:
Below we list the standard ISO tolerances for precision ground, bright drawn, smooth turned and polished round steel bar (diameters). Below we list details of the popular ISO h tolerances, we can also produce to tight tolerances to ISO 286 such as g5, g6, d8, d9 etc. ISO 286-2 Round Bar Tolerances - Metric Metal Parker ISO 286-2 Round Bar Tolerances Tolerances are all plus 0mm, - mm size. Parenthetical numbers indicate inches. Refer to the above chart for the following example:Example:a 20mm Round h9 will have a tolerance of + 0mm, - 0.052mm which equals + 0, - 0.00205 Equivalent German Specications DIN 668 = h11 DIN 669 = h9 DIN 671 = h9 DIN 175 = h9 Stainless Steel - General Information - EN Standards for H = All Minus Tolerance e.g. 45mm dia.

Our ground round bar is available in steel grades with improved machinability, corrosion resistance, ductility, formability and strength. With a ground bar from us, you get a stainless bar well suited for mass production of small parts with high demands on surface roughness, straightness and small tolerances. Stainless steel round bar - YAMCODrawing (CD, finished) - Stainless steel round bar -. CD stands for "cold drawing." The material has been drawn through a steel die without being heated. The surface has a glossy finish. Achieves better dimensional accuracy than with peeling or pickling. Generally of Class h9 tolerance. Grade. Standards and tables - Rodacciai135. The diameter of a bar, measured at any point at least 100 mm from the ends, must be within the tolerances indicated in the table. Unless otherwise agreed, shearing may deform the ends of the bars. Straightness tolerances for hot rolled bars (UNI EN 10060:2004) Nominal diameter (mm) Tolerance (mm) d 25. 25 < d 80.
Square bars:20 400 mm. Bars length:L = 2.000 12.000 mm (or on request) For square and flat bars there are various options for radius and round-edged corners according to EN 10058, EN 10092 or on request. We offer also hot rolled bars with peeled surface in tolerance H11 or H13.
