GB 35CrMo, Cr-Mo alloy structural steel
35CrMo
35CrMo round bar for application-ready supply.
Cr-Mo alloy steel for high-strength fasteners, shafts, pressure-related parts, and industrial components.
Procurement Summary
Technical points buyers normally confirm first.
Use this page as a starting point for RFQ discussion. Exact chemistry, mechanical properties, delivery condition, testing, and certificate requirements should be confirmed against the active order standard.
Delivery and surface routes
- QT depending on project
- Hot rolled
- Threading preparation
Inspection discussion
- Chemical composition verification
- Mechanical testing
- Dimensional inspection
What buyers should confirm
- Equivalent standard and active order specification
- Diameter, length, tolerance, and quantity
- Delivery condition and surface route
- Processing needs such as cutting, peeling, grinding, threading, or machining preparation
- Testing, certificate, traceability, packing, and destination requirements
Buyer Fit
When buyers choose 35CrMo.
Buyers commonly review 35CrMo for fasteners, threaded rods, shafts, and heavy machinery components that need a Cr-Mo alloy structural steel route.
Choose this grade when
- The application is a high-strength fastener, threaded rod, shaft, or machinery part.
- The process route includes QT, peeling to rolling diameter, thread rolling, surface treatment, and inspection.
- The buyer needs grade, strength target, threading route, and document scope reviewed together.
When to review another route
Review 42CrMo4 when the buyer needs a more internationally recognized equivalent family or a different alloy route for hydraulic or shaft applications.
Example RFQ
35CrMo round bar, Dia 32mm x 6000mm, QT, peeled to thread rolling diameter, 15MT, for high-strength threaded rods, destination Manila, MTC required.
Application Fit
Typical application routes.
Confirm grade, delivery condition, surface route, testing requirements, and downstream process before final quote.

Private Factory Processing
Processing support can be matched to the order route.
Processed through JOTAIN's private factories when project requirements call for heat treatment, peeling, grinding, straightening, chrome plating or cut-to-length preparation.
Factory capability
Review JOTAIN's heat-treatment and bright-bar processing factories before confirming delivery condition, surface route, inspection, and packing requirements.
Processing & RFQ
Connect grade choice with the required supply route.
Before quotation, confirm the processing route and document package together with the grade. This helps avoid quoting a bar that matches the grade name but not the downstream manufacturing need.
Discuss QT, normalized, or annealed route when the application requires controlled condition.
Review surface and dimensional expectations before machining or assembly.
State MTC, testing, traceability, and third-party inspection needs during RFQ review.

FAQ
Common buyer questions.
Is 35CrMo the same as the listed equivalent standards?
35CrMo is commonly discussed with GB 35CrMo, Cr-Mo alloy structural steel. Final equivalence should be confirmed against the active order standard, drawing, and property requirements.
What delivery condition should I specify for 35CrMo?
Common discussion points include QT depending on project, Hot rolled, Threading preparation. The right condition depends on downstream application, machining route, and inspection requirements.
What applications use 35CrMo?
35CrMo is commonly discussed for Fasteners, Threaded rods, Shafts, Heavy machinery. Buyers should confirm load, surface route, and document requirements before quotation.
What should I include in an RFQ?
Share fastener or shaft route, target mechanical properties, quantity, and certificate needs.
