What is the approximate heat treatment cost for H13 material?
Leave a message
H13 material usually costs between 800 and 2000 RMB per ton for heat treatment. The size of the workpiece, the kind of heat treatment procedure (such as nitriding or tempering), the batch size, and the area or service provider all affect the final cost. Costs will increase for larger workpieces or more intricate procedures (such vacuum heat treatment).
1. Heat treatment's primary cost components
The item
Price Range
An explanation
Tempering and Quenching (Quenching + Tempering)
800–1500 RMB per ton
The majority of molds and hot runner systems can benefit from basic heat treatment, which raises hardness to 48–52 HRC.
Surface Strengthening (Nitriding)
1200–2000 RMB per ton
enhances wear resistance and surface hardness; frequently applied to important parts like manifolds and nozzles
Treatment using Vacuum Heat
1500–2500 RMB per ton
Prevents oxidation and deformation; more expensive but stable quality; appropriate for high-precision workpieces
Tempering Stress Reduction
500–800 RMB per ton
Prevents deformation and removes residual stress after processing; frequently used as a pre-processing phase
Case Study: At a cost of 1850 RMB per ton, a Wuhan-based manufacturer treated H13 hot runner components with a combination of quenching, tempering, and nitriding.
2. Important Cost-Affecting Factors
Workpiece Size and Weight: Bigger workpieces necessitate longer holding times and larger furnace chambers, which raises unit costs.
Batch Size: Bulk deliveries may be eligible for savings; single-piece or small-batch processing has a higher unit charge.
Process Complexity: Energy and labor consumption are increased by multi-stage heat treatment (e.g., preheating + quenching + repeated tempering).
Service Provider Type: Although professional heat treatment facilities, like Wuhan Heat Treatment Plant, are more expensive than standard processing facilities, their procedures are more dependable.
To maintain process traceability, pick a service provider who has hardness test data and furnace temperature profile records.
3. Suggestions for Cost Reduction
Centralized Batch Processing: To save unit costs, combine several workpieces for heat treatment.
Give Local Service Providers Priority: Cut down on travel and wait times. Wuhan Heat Treatment Plant and Jingmo Technology are two examples of local service providers.
Optimize Process Flow: Steer clear of repetitive heating and plan the final heat treatment and stress release steps logically.
"One-time completion, full traceability" is a safety principle that guaranties consistent heat treatment quality and prevents higher expenses from rework.
