RFQ checklist
- Grade and equivalent standard
- Diameter, length, and quantity
- Target properties or active specification
- Testing, certificate, and destination

What QT Condition Means in Alloy Steel Bars
QT means quenched and tempered. For alloy steel bars, QT language should always be connected to grade, size, target properties, order standard, and downstream use.
Quick Answer
What buyers should know first.
QT means quenched and tempered, but buyers still need to state grade, standard, size, target properties, test scope, and certificate requirement.
RFQ Comparison
Connect the topic to quotation impact.
| Topic | What to review | RFQ impact |
|---|---|---|
| Condition | QT, hot rolled, normalized, or other delivery condition | Prevents mismatch between quoted route and required performance |
| Properties | Active standard, target mechanical properties, and test method | Defines what the heat-treatment route must support |
| Inspection | UT, dimensional checks, MTC, or third-party inspection | Clarifies cost and timing before order |

Buyer Guide
What to review before quotation.
Use this guide to prepare a clearer specification and reduce back-and-forth during RFQ review.
Why QT matters
QT condition is requested when buyers need a controlled strength and toughness route for components such as shafts, rods, fasteners, and heavy machinery parts.
What not to assume
Do not assume a single universal property level from the letters QT alone. The required standard, diameter, heat-treatment route, and test scope should be stated clearly.
RFQ details to include
Send grade, equivalent standard, diameter, length, quantity, target condition, target mechanical properties if known, test items, certificate requirements, and destination.

FAQ
Common buyer questions.
Does QT always mean the same strength?
No. QT condition must be tied to grade, size, order standard, and target mechanical properties.
Should I request mechanical testing?
For demanding applications, state the required test items and certificate format during RFQ review.
Can JOTAIN review QT requirements before quote?
Yes. Send the grade, size, condition target, application, and document requirements for review.
