From Raw Materials To Delivery: Supply Chain Optimization Practices for Martensitic Stainless Steel Materials

——How do we achieve efficient, stable and controllable delivery capabilities?

As competition in the manufacturing industry becomes increasingly fierce, material suppliers must not only provide high-quality products, but also continuously optimize delivery efficiency, quality traceability and customer service. As a professional supplier focusing on martensitic stainless steel materials, DSM always insists on controlling quality from the source and optimizing processes from details to ensure that each batch of steel can be delivered to customers on time and with high quality.

This article will give you an in-depth understanding of our company's actual practices in the martensitic stainless steel material supply chain.

1.Strict selection of raw materials to ensure stable performance

High-quality martensitic stainless steel comes from high-quality raw materials. We have long-term cooperation with stable upstream smelters, and select alloy raw materials with precisely controlled chromium and carbon content to ensure uniform composition and high purity. Before each batch of raw materials is put into storage, it must pass spectral analysis and initial metallurgical structure inspection to prevent inclusions and material deviations.

Representative steel grades: MMB6, MMB6C, 420J2, 420J1, 5Cr15MoV, etc.

Control focus: precise control of carbon content, control of non-metallic inclusions, and consistency of composition

2.Precision control production to meet customized needs

We have a complete production and processing line, and can provide full-process, multi-process processing services according to the different needs of customers, meeting the diverse requirements from original rolls to terminal applications. Our core processing capabilities include:

• Cold rolling processing - improving surface and thickness accuracy

The cold rolling unit is used to roll stainless steel billets in multiple passes. The products have the advantages of smooth surface, precise thickness control, and stable mechanical properties. It is suitable for tools, precision parts and other fields that require high thickness tolerance and surface quality.

 Slitting processing - flexibly meet width specifications

The mother roll material can be slit into small rolls of different widths according to customer requirements, and the edges are controlled to be neat and burr-free. It is widely used in the preparation of the front process of products such as blades and metal stamping parts.

Shearing & Cutting - precise size, smooth as a mirror

Equipped with CNC shearing and leveling equipment, it can achieve the fixed-length shearing and leveling of stainless steel coils, ensuring that the plates are flat and wave-free with high dimensional consistency, suitable for subsequent laser cutting or stamping processing.

• Heat treatment service - the core link of performance control

We are equipped with multiple sets of heat treatment equipment such as quenching furnaces and tempering furnaces. We can customize the heat treatment process route according to different steel types and uses to achieve the required mechanical properties such as hardness, strength, and toughness.

Processing advantages at a glance:

• Supports personalized customization of fixed specifications, fixed thickness, and fixed hardness

• Regular tolerances are better than national standards and meet high-end processing requirements

• Quickly switch production batches to meet the delivery needs of small batches and multiple varieties

We are not a simple material supplier, but a front-end supporter of the customer's processing process. Your usage scenario is the starting point for us to develop the process.

3. Full-process quality inspection to ensure that every batch is qualified

Quality is not the last step, but a management throughout the entire process. We have set up strict quality inspection procedures in the following links:

• Cold rolling stage: Dual guarantee of thickness and surface quality

Real-time online thickness monitoring to ensure stable control within tolerance

Surface defect inspection (scratches, indentations, oxide scale) is double-checked by manual + equipment

Initial inspection of material mechanical properties to ensure that the cold rolling process does not cause performance fluctuations

Heat treatment stage: full inspection of key points of performance control

Hardness test: sampling or full inspection by batch, using Rockwell/Vickers hardness tester

Metallographic analysis: metallographic structure inspection of key batches to prevent overburning or abnormal martensitic structure

Performance tracking record: record of setting parameters for each furnace + test data for more than 2 years for quality traceability

Finished product factory inspection and archiving

All inspection data are entered into the system to generate a complete quality inspection report

Each batch of products is accompanied by a label with clear information for easy storage and sorting

All factory products can provide a complete quality inspection report to meet customers' requirements for quality visualization and traceability.

4. Standardized packaging to ensure transportation safety

All packaging is checked for earthquake resistance, moisture resistance, and pressure resistance before transportation to ensure that it will not shift, scratch, or deform during long-distance logistics, ensuring that the product is delivered to the customer in the best condition.

5. Chartering and booking, efficient delivery

6. Use services to get through the last mile

We know that customers are most concerned not only about the materials themselves, but also about the controllability of delivery and the responsiveness of services. Therefore, we promise:

Communicate production plans in advance and make delivery dates clear

Quickly respond to problems and provide solutions within 48 hours

Provide full-process tracking services: real-time feedback from order to delivery

In the sub-segment of martensitic stainless steel materials, we always believe: "Product strength + service strength = long-term customer trust". From raw material selection, production and processing to quality inspection packaging and delivery and transportation, we strive for excellence in every link, just to make customers feel at ease and satisfied.
