Grade 50 Carbon Steel Strip: Raw Material and Post-Processing for Mechanical Sheet Parts
Published
Grade 50 medium-carbon steel strip is often used for perforated mechanical limit plates and similar drawing-based parts. Purchasers must distinguish supply condition from post-treatment hardness, deformation, and dimensions; pre-production samples should complete the full process, with punched and trimmed edges included in acceptance. Jiangsu Gaozhen handles enquiries by grade, dimensions and processing requirements.
50#: material and applications
Grade 50 is a common medium-carbon steel grade, listed as cold-rolled carbon steel strip in the Gaozhen product catalog. It suits mechanical sheet parts requiring moderate strength and possible subsequent heat treatment, such as limit plates, shims, and connecting plates. Its selection value lies in managing the raw material condition and treatment route separately: purchasers can choose the supply condition for forming needs, then arrange treatment according to part service requirements. Finished hardness cannot be promised based on grade alone, as it depends on actual heat treatment conditions. For perforated limit plates, the material should meet punching, trimming, and flatness requirements while leaving room for deformation control in later processing.
Typical Parts and Processing Flow
Perforated mechanical limit plates are typical drawing-based parts, usually made from cold-rolled steel strip through punching, trimming, possible bending or sizing, and then post-treatment. Processing should focus on punched and trimmed edge quality, as edge condition can affect post-treatment deformation and acceptance. Pre-production samples should complete the full flow, including blanking, punching, trimming, and post-treatment, to evaluate dimensional changes and flatness. For limit plates with hole spacing and profile requirements, die clearance and edge condition should be adjusted based on trial punching results. Post-treatment deformation should be confirmed by measuring samples, not inferred from raw material condition alone.
Purchasing Points and Rationale
For Grade 50 strip, specify annealed or another agreed delivery condition, gauge and width tolerances, surfaces and edges. Where later treatment is required, distinguish stock acceptance from the finished part’s hardness and dimensions.
Give measurement criteria for the limit plate’s hole spacing, outline and flatness on the drawing. Inspect samples after blanking, trimming and post-treatment to observe changes across the full route. Relate production stock to the approved condition and update the material list when the process or dimensions change.
Is Harder Raw Material Better for Blanking?
Not necessarily. Higher raw material hardness may change punching and trimming edge loads, burr patterns, and die wear, but blanking success also depends on die clearance, edge condition, and lubrication. If subsequent forming or post-treatment is needed, harder raw material may limit forming margin. Purchasers should evaluate based on the forming and treatment route rather than pursuing high hardness alone.
50# dimensions and supply enquiry
The Gaozhen 50# product page lists these catalogue dimensions: Thickness range: 0.2-6.0 mm; Width range: 8-350 mm. These values support specification discussions; confirm the required combination of gauge, width and condition for the material.
For carbon strip, provide blank dimensions, delivery condition and later processing. Distinguish stock dimensions from finished dimensions where grinding, forming or treatment follows.
