Stainless Steel 202 needle tubes from Sumer Metal Industries Private Limited are manufactured for high-volume medical, industrial and precision applications where cost-effectiveness and good mechanical strength are required. Sumer Metal Industries produces these needle tubes using controlled cold-drawing and precision finishing processes to deliver tight dimensional tolerances, consistent wall thickness, smooth inner/outer surfaces and superior straightness — qualities essential for needles, capillaries, hypodermic applications, and fine instrumentation. The company emphasizes ISO-aligned quality controls and batch traceability for every shipment.
The alloy choice — SS 202 — provides a balanced combination of corrosion resistance and higher mechanical strength compared with 300-series stainless steels at a lower cost because of reduced nickel content. Sumer’s production line for SS202 needle tubes typically includes pickling, annealing (where applicable), straightening, cold drawing to finished size, and final testing (visual, dimensional, and hardness checks). Surface finishes available include bright-drawn, polished ID/OD, and passivated finishes tailored to customer requirements.
Sumer Metal Industries positions itself as a manufacturer, supplier and exporter: they supply domestic markets and export SS202 needle tubes to Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada and several regions across Africa. Export packaging, customs documentation, and international shipping practices are handled to meet importer and regulatory requirements; the company can provide specific export documentation (COO, test certificates, mill certs) on request to facilitate customs clearance and procurement procedures in receiving countries.
Typical applications for SS 202 needle tubes include medical needle blanks, cosmetic and acupuncture needles, fluid dispensing capillaries, small-bore fittings, instrumentation tubes, and specialty fasteners where a combination of formability, strength and corrosion resistance is required. SS 202’s higher manganese and lower nickel content make it suitable for many of these applications where exposure is to mild corrosive environments (e.g., indoor/controlled atmospheres, non-marine ambient conditions).

Quality and compliance are central to Sumer’s offering: they test products against dimensional tolerances and mechanical property targets, provide mill test reports, and can produce tubes to customer-specified tolerances, including concentricity and ovality limits for precision needle applications. The company also offers secondary services such as cutting to length, end deburring, end chamfering, and small-batch kitting to support OEM production lines and contract manufacturers in the export markets named.

A1: Use targeted, buyer-intent phrases such as "SS202 needle tubes", "Stainless Steel 202 needle tubing", "precision needle tubes manufacturer", "SS202 needle tube exporter", combined with region-specific tags like "export to UAE" or "supplier in Germany". Avoid keyword stuffing — keep 6–10 relevant keywords.
A2: Write a concise, benefit-driven meta description (120–160 characters) that includes product name and selling points, e.g., "Sumer Metal Industries — Precision SS202 needle tubes: bright-drawn, tight tolerances, export-ready to UAE, Saudi, EU & North America."
A3: Use a clear H1 with the product name, descriptive alt text for images (e.g., "SS202 bright-drawn needle tube 1.0mm OD"), structured data (Product schema), unique product descriptions, and metadata (title, meta description, meta keywords) aligned with buyer intent and export markets.
