42CrMo4 Round Bar: Frequently Asked Questions

Straight answers on sizes, thickness, weight, grades, MTC, pricing and ordering ā€” so your enquiry is specification-ready before you send it.

01
What is 42CrMo4 Round Bar?
42CrMo4 Round Bar are chromium-molybdenum alloy steel round bar used for highly stressed engineering components. The exact diameter, grade, standard, supply condition and intended use must be stated because the commercial product name alone does not establish chemical, mechanical, dimensional or heat-treatment requirements.
02
What are the main applications of 42CrMo4 Round Bar?
Common applications include gears, crankshafts, axles, bolts, shafts and heavy machinery parts. Suitability depends on the component design, loads, environment, machining allowance, heat treatment and governing code. Final selection must follow the approved drawing, BOQ, end-user specification and responsible engineerā€™s approval.
03
Which diameters are listed for 42CrMo4 Round Bar?
The live round-bar chart lists 10, 12, 14, 16, 18, 20, 22, 24, 25, 28, 30, 32, 34, 36, 40, 45, 50, 56 and 60 mm. These published entries are not a guarantee of current stock. Confirm the exact diameter, grade, length, condition and quantity, particularly when a machining drawing requires an unlisted size or minimum clean-up allowance.
04
How should I specify the diameter and tolerance for 42CrMo4 Round Bar?
State the nominal diameter in millimetres, applicable diameter tolerance, ovality if relevant, straightness and surface condition. For machined parts, add the finished component size and machining allowance. Bright, peeled, ground and hot-rolled bars may have different dimensional expectations.
05
What standard lengths are available for 42CrMo4 Round Bar?
The reviewed page does not publish a fixed length range. Availability should be confirmed for the requested diameter, grade and quantity. State exact or random length, permissible tolerance, cut-length schedule, end condition and whether each piece must be identified to a drawing item.
06
How is 42CrMo4 Round Bar weight per metre calculated?
For a solid steel round bar, theoretical weight in kg/m is approximately diameter squared x 0.006165, using nominal dimensions and a typical steel density. Actual or invoiced weight may differ because of diameter tolerance, density, scale, length and the agreed commercial basis.
07
Can I get a 42CrMo4 Round Bar weight chart?
Yes. The live page provides average kg/m and kg/ft values for listed diameters. Use them for estimation, then confirm the quotation basis and applicable dimensional tolerances. For alloy or special-condition material, ask whether the supplier uses theoretical or actual weighment.
08
What is the 42CrMo4 Round Bar price per kg?
The price per kg requires a dated quotation and varies with grade, diameter, quantity, supply condition, finish, testing, cutting, packing, freight and taxes. Alloy surcharge and heat-treatment condition can be important for engineering grades. Send a complete specification for a comparable rate.
09
How is the 42CrMo4 Round Bar price per tonne determined?
Price per tonne depends on the exact grade and standard, diameter mix, bar length, total tonnage, condition, certification, inspection and destination. Confirm whether cutting, heat treatment, testing, packing, freight and GST are included and check the quotation validity.
10
What is the MOQ for 42CrMo4 Round Bar?
The live page states a minimum order quantity of 1 tonne. Actual order acceptance remains subject to the required diameter, grade, condition and availability. For mixed-diameter orders, give the piece count or weight for each line item so every size can be reviewed.
11
Is 42CrMo4 Round Bar available from ready stock?
Stock must be confirmed for the exact diameter, grade, standard, length, finish, condition and quantity. A live product page or size chart does not establish immediate availability. State any mill or make preference, MTC requirement, inspection plan and required delivery date.
12
Can an MTC be supplied with 42CrMo4 Round Bar?
Request the mill test certificate at enquiry stage and state the required document type. It should identify the material, heat or batch, grade, standard and reported chemistry and mechanical results where applicable. Heat-treatment condition, hardness and traceability requirements should be agreed before ordering.
13
Which heat-treatment condition should be ordered?
State annealed, normalised or quenched-and-tempered condition, required hardness range, diameter and mechanical-property specification. Diameter and quenched-and-tempered condition materially affect achievable mechanical properties. Machining allowance and subsequent heat treatment should be planned with the component manufacturer.
14
Can 42CrMo4 Round Bar be cut, machined, threaded or heat treated?
Processing can be reviewed against the drawing, grade, condition and quantity. Provide cut lengths, tolerances, thread details, machining allowance and required heat treatment or hardness. Final component properties cannot be guaranteed from the bar designation alone; the approved manufacturing route controls the result.
15
Can 42CrMo4 Round Bar be replaced with an equivalent grade?
Do not substitute from a web equivalence table alone. Compare full chemistry limits, mechanical properties, diameter-dependent requirements, delivery condition, hardenability, impact quality, heat treatment and certification. Any alternative requires written approval from the responsible engineer or end user before supply.
16
Can I buy 42CrMo4 Round Bar from a supplier in Mumbai or Navi Mumbai?
Ferrite lists its head office in Mumbai and a facility address at Kalamboli, Navi Mumbai. Provide delivery postcode, longest length, total tonnage, unloading constraints and required date so availability and logistics can be reviewed for Mumbai, Navi Mumbai and Maharashtra.
17
Can 42CrMo4 Round Bar be supplied across India?
The website states nationwide supply. India-wide enquiries should include the consignee postcode, grade, diameter, length, tonnage, packing and delivery schedule. Long-bar freight can materially affect landed price, so compare offers on the same ex-works or delivered basis.
18
Does Ferrite handle export enquiries for 42CrMo4 Round Bar?
Export requirements can be reviewed against the requested specification and quantity. Provide destination port and country, Incoterm, grade, standard, diameter, length, tonnage, condition, packing, MTC and inspection requirements. Shipping programme and documentation must be confirmed for the specific order.
19
How should quotations from 42CrMo4 Round Bar suppliers be compared?
Compare the exact grade, standard, diameter tolerance, length, condition, origin or make if specified, MTC, inspection, cutting, packing, freight, taxes and delivery basis. A lower rate is not comparable if the offered condition, certification or heat-treatment scope differs.
20
What details are needed for a fast 42CrMo4 Round Bar quotation?
Send product name, complete grade and standard, diameter, length, piece quantity and total tonnage. Add finish and delivery condition, tolerance, make preference, MTC, inspection or ultrasonic testing, cutting drawing, delivery postcode or destination port, Incoterm and required delivery date.
