| Mechanical reference — 16–95 mm | Rp0.2 ≥305 MPa · Rm ≥580 MPa · A ≥16% | CBR 150 web table uses 16–95 mm; source thresholds and the 95–100 mm gap need confirmation. |
| Mechanical reference — Ø≥100 mm | Rp0.2 ≥275 MPa · Rm ≥560 MPa · A ≥16% | Source delivery condition is not explicit; confirm before design or purchase. |
| Other reference-family grades | C35 · 20MnV(S)6 · 38MnV(S)6 · X20Cr13 · 310 · 316 | Additional source grades, not equivalents to this product. Ask for separate MYLER availability and grade-specific chemistry/mechanical properties. |
WHAT TO SPECIFY
The specification depends on the part and its application. Confirm the grade, dimensions, chrome surface, end details and inspection requirements for each drawing reference.
Dimensions & fit
02
Provide finished diameter, length and all tolerances affecting fit. Include straightness, roundness and other geometric requirements where they appear on the drawing or are needed for assembly.
Chrome surface
03
State chrome layer and surface finish requirements, including any acceptance limits and inspection method. The coating scope is confirmed with the order rather than inferred from the product name.
Inspection records
04
Identify the dimensional, material and surface records needed for acceptance. The document type, traceability requirements and inspection scope are reviewed against the order specification.
Machining details
05
Include chamfers, threads, holes and other end details on the current drawing. Machining scope, tolerances and any subsequent surface requirements need to be confirmed together.
Drawing review
06
Bring material, dimensions, machining, finish and inspection requirements into one drawing review. Each feature can then be checked against the requested supply condition and any open points recorded before ordering.

OUR PROCESS
From first drawing to agreed requirements
Review the requirements in sequence: drawing, material, dimensions, surface and acceptance records. Resolve open points before confirming the order.
StepDrawing review001
Start with the part
Send your drawing, revision, requested quantity and application. Identify the features and operating conditions that influence material selection, surface requirements or inspection.
StepMaterial condition002
Confirm before ordering
Review the C45 designation, applicable standard and requested delivery condition. If an alternative is proposed, check the differences against the drawing and agree the change in writing before ordering.
StepDimensions & ends003
Check the complete geometry
Review diameter, length, fit tolerances, straightness and all specified end features. Include machining requirements and the current drawing revision so the complete geometry can be assessed.
StepSurface & inspection004
Define acceptance criteria
Confirm chrome layer, roughness and the inspection scope needed for the working surface. State the required records and acceptance limits so they form part of the reviewed order specification.
StepOrder confirmation005
Agree the supply scope
Confirm material, dimensions, finish, quantity and documents in writing. Standard packing is paper wrapping followed by wooden cases to help protect against scratches and knocks. Agree delivery timing and any special packing needs before ordering.
StepRecords & release review006
Keep requirements connected
Check the specified records and identification against the agreed order. Review any changes or deviations before release, and retain the drawing reference for subsequent enquiries.

FREQUENTLY ASKED QUESTIONS
Start with the drawing and the required condition.
The chrome-bar reference groups several grades for surface properties. Chemistry, core properties and delivery condition remain grade-specific; 304, C45 and 42CrMo4 are not interchangeable.
Send your drawing and required parameters for review. Material, dimensions, surface requirements and acceptance criteria are confirmed in the quotation.
Send the exact product, material, delivery condition, dimensions, quantity and drawing. Specify tolerances, roughness, straightness, hardness, inspection records and any special packing requirements.
State the required chrome layer, surface roughness and associated acceptance limits. These requirements, their inspection method and the agreed supply scope should be confirmed before ordering.
