Product information

60CrMoV18-5 takes "high wear resistance + high temperature stability + corrosion resistance" as its core advantage. It is an ideal material for heavy-duty stamping dies, corrosive plastic dies and high-temperature tools. The comprehensive technical parameters summary of 60CrMoV18-5 die steel (German grade 1.2358) is based on ISO 4957/DIN EN 4957 standards and production practices, covering key information such as smelting process, material characteristics and application scenarios.

 

Smelting method

Mainstream process: EAF primary smelting + LF ladle refining + VD vacuum degassing: basic desulfurization (S ≤ 0.030%), dephosphorization (P ≤ 0.030%) and composition control.

Upgraded Process: Electroslag Remelting (ESR): deep purification, reduction of non-metallic inclusions, improvement of isotropy (for high-end applications).

Vacuum refining technology: further reduce the gas content (O ≤ 20 ppm) to prevent white point defects.

FAQ


Q How should I choose the right die steel material for my die?

Ans: There are several key factors to consider when selecting a die steel, including: Mold use: injection molding? Die casting? Stamping? Cold work? Hot work? Processing material: plastic type (including glass fiber?) , metal type, yield requirements. Performance requirements: wear resistance, toughness, corrosion resistance, high temperature strength, polishing, dimensional stability. Budget: The price of different material grades varies greatly. Processing conditions: working temperature, stress, cooling mode. Suggestion: Provide as much detail as possible about the application of the die, or contact our technical sales team directly, and we will recommend the most suitable material grade according to your specific needs.

Q Is the die steel provided by you genuine? How to ensure the quality of materials?

Ans: Yes, the die steel we provide is produced and processed independently. We have long-term cooperation with first-line brands at national and abroad to ensure that all materials are genuine. We provide a complete original warranty (material certificate), including key data such as chemical composition and physical properties. We will also carry out strict factory re-inspection of some materials to ensure that the quality meets the standards.

Q The price of die steel fluctuates greatly. What are the main factors affecting the price?

Ans: The price of die steel is mainly affected by the following factors: Raw material cost: market price fluctuation of alloy elements (such as chromium, molybdenum, vanadium, tungsten, etc.). Production process: ESR, VD/VAR and other special processes increase the cost. Grade and brand of material: The price of material with high performance and famous brand is higher. Specifications and sizes: Premium prices may apply for special sizes, large sizes, or small quantities. Market supply and demand: changes in supply and demand in global and regional markets. Processing state: the price of pre-hard state (such as P20, 718, NAK80, etc.) Is higher than that of annealed state. We will provide a transparent and reasonable quotation according to the market situation.

Q What is time for delivery?

Ans: The delivery time depends on: Material inventory status: Common brands and specifications We usually have in stock, can achieve faster delivery (for example: 1-3 working days). Material specification and status: special size, uncommon brand or special treatment (such as pre-hardening, deep processing) may need to be ordered, the cycle is relatively long (for example: 1-6 weeks). Order size: Large orders may require coordinated production scheduling. Please tell us your specific requirements (brand, specification, status, quantity) at the time of inquiry, and we will provide the most accurate delivery information.

Q Can you provide heat treatment or processing services after the purchase of die steel?

Ans: Yes, we provide complementary professional services: Heat treatment: With professional heat treatment equipment (vacuum quenching, cryogenic treatment, tempering, etc.) And strict process control, we can provide customers with precise heat treatment services (according to material brand and hardness requirements). Finish machining: We can provide precision machining services such as milling, grinding (surface grinding, internal and external grinding), wire cutting, EDM, etc. According to customer's drawings. Please provide your specific needs (drawings, technical requirements), and we will evaluate and provide quotations and service programs.

Q The mold cracks and wears too fast during use. What are the possible reasons? Is it related to the material?

Ans: The causes of mold failure are complex and diverse, which may be related to materials, but also involve many links such as design, processing, heat treatment, service conditions, etc.: Material factors: improper selection of materials (performance does not match the working conditions), internal defects of materials (inclusions, segregation), counterfeit and shoddy materials. Heat treatment factors: Improper process leads to poor structure, uneven hardness and excessive residual stress. Design/processing factors: stress concentration, poor surface roughness, too deep tool marks. Usage factors: overload, insufficient lubrication, poor cooling, improper maintenance. Suggestion: In case of failure, please provide detailed information as much as possible (material grade, heat treatment status, photos of failure location, description of working condition). Our technical team can assist you in preliminary analysis to determine whether it is related to the material or provide suggestions for improvement.

Q Do you have a minimum order quantity (MOQ) requirement for your die steel products?

Ans: For the stock of conventional grades and specifications, we usually do not have strict MOQ restrictions, and can be purchased according to the actual needs of customers. For materials requiring special orders (such as unusual grades, special sizes, customized heat treatment/processing), Certain MOQ requirements may be set to ensure the economy of production, usually a minimum of 8 tons. Please consult our sales staff for specific MOQ before placing an order.

Q In addition to standard grades, can you offer special die steels with custom compositions?

Ans: We mainly deal in standard grades of die steel, which are widely proven to meet the needs of most applications. For the development of customized alloys with special performance requirements, this usually involves a large amount of R & D investment and production coordination, which is costly and takes a long time. We recommend that priority be given to the material closest to the demand from among the existing mature grades, or to meet special requirements by optimizing the heat treatment and surface treatment. If there is a need for customization, please specify the technical requirements and we will evaluate the feasibility.
