OUR APPROACH

Induction hardening treats the steel below the chrome. Select the base grade, hardened depth and coating finish as separate requirements.

The result is a clear set of requirements for the material, hardened layer and chrome surface, linked to the records needed for acceptance.

Parameter	Reference value	Application / confirmation
Reference base grades	C35 · C45 · C55 · Cf53 · 42CrMo(S)4 · 20MnV(S)6 · 38MnV(S)6 · X46Cr13	Catalogue CBI family; grade availability and compatibility require confirmation.
Diameter	10–160 mm	Confirm the order requirement with your quotation.
Diameter tolerance	f7	Confirm the order requirement with your quotation.
Chrome thickness	150: ≥12 · 250: ≥20 · 500: ≥30	Raw source minima: units are omitted in the coating-thickness column. Confirm the unit before using these values in an order.
Chrome-layer hardness	≥1000 HV0.1	Chrome coating only. This value does not describe the core or induction hardened layer.
Surface roughness	Ra ≤0.10 · Rt ≤1.00	Raw source Ra/Rt values; the chrome tables omit their unit. Confirm the unit, test method and sampling length.
Ovality	≤ ½ of the diameter tolerance	Confirm the selected diameter tolerance and measurement method.
Straightness	≤0.2 mm/m	Agree measurement length and support conditions.
Microcrack density	≥6000 microcracks/mm²	Catalogue coating characteristic; not a MYLER inspection result.
NSS corrosion reference	150: R10 150 h / R9 300 h; 250: R10 250 h / R9 500 h; 500: R10 500 h / R9 1000 h	Source finish classes only. Test: ISO 9227; evaluation: ISO 10289. Request order-specific test evidence.
Length	Confirm for the order	No universal length is stated in the referenced product table.
Hardened-layer hardness	42–62 HRC	Family reference across grades and diameters; select an actual acceptance band for the ordered grade.
Hardening depth by diameter	Ø10: 0.7–0.9; Ø12–18: 0.9–1.1; Ø20–30: 1.2–1.4; Ø30–60: 1.4–2.5; Ø60–80: 2.5–2.7; Ø80–160: 3.2–5.0 mm	Source diameter bands overlap at their boundaries and omit some sizes. Confirm the exact diameter, grade and effective-depth criterion.
Source correction	Use catalogue CBI 150 / 250 / 500 tables	The web CBI 250/500 detailed tables repeat 150-class values. Catalogue physical pages 11–12 distinguish the three classes.

WHAT TO SPECIFY

Define the base material, hardening requirements, dimensions and chrome finish for the application. The following points provide a complete enquiry checklist.

START AN ENQUIRY

Base material

State the base material designation, applicable standard and delivery condition. Any alternative material must be reviewed against the drawing and agreed before it replaces the specified grade.

Finished dimensions

Provide finished diameter, length and fit tolerances. Include all end features and any allowances that influence the required supply condition or subsequent machining.

Surface hardness

State the required surface hardness, its scale, measurement location and acceptance limits. The test method and reporting requirements must be confirmed against the drawing.

Hardening depth

Define the required hardening depth and the criterion used to measure it. Include the relevant test method and acceptance limits so the hardened layer is specified unambiguously.

Chrome layer

Specify the chrome layer requirements for the working surface, including acceptance limits and inspection method. Confirm their relationship to the hardened layer and finished diameter.

Surface roughness

State the required roughness and which surface it applies to. Include the measurement method and acceptance criteria where they are specified by the drawing or application.

Geometry & ends

Include straightness, roundness, chamfers, threads and any other specified end features. Review machining details together with the hardened and chrome-coated surface requirements.

Inspection records

List the material, hardness, depth, dimension and surface records required for the order. Agree the document type, traceability and inspection scope before supply.
