Cast Female HT300 Iron Thread Tee
Custom Iron Casting & Machining Service — From Your Drawing to Finished Parts
This Cast Female HT300 Iron Thread Tee is a core pipeline branching and distribution component designed for industrial compressed air distribution systems. It is manufactured by our in-house Sand Casting + CNC machining and threading process to achieve high strength, precise geometry, and reliable thread sealing. The use of grey cast iron HT300 provides an excellent balance of high tensile strength (≥300 MPa), superior wear resistance, and excellent vibration damping capacity — delivering a fitting that maintains dimensional stability under high-pressure conditions, threads cleanly for leak-free assembly, and withstands mechanical stress and thermal cycling in heavy-duty piping systems.
Matech's one-stop approach, covering pattern making, sand casting, stress relieving heat treatment, CNC machining and precision threading, hydrostatic pressure testing, surface treatment (anti-rust oil/coating), and engineered packing, ensures this tee offers excellent pressure tightness, performing reliably in demanding high-pressure industrial piping and fluid distribution environments.

Our Advantages
Technical Advantages
1
Pattern shop, shell molding & resin sand casting lines, CNC machining, heat treatment, and inspection lab — all centralized under one roof. No outsourcing. From base iron melting to finished and coated part, we maintain full control over lead time, quality consistency, and batch traceability.
2
Before pattern production begins, we provide a detailed DFM report covering solidification behavior, graphite morphology control, gating & riser design, core assembly strategy, and machining allowance optimization. We flag potential shrinkage areas and hard spots early, helping you refine the design for better castability and lower cost.
3
We specialize in geometrically demanding parts with complex internal cavities, multi-core assemblies sections — such as chasis brackets, valve bodies, gearboxes, engine blocks, and cylinder heads. Our shell molding process delivers superior surface finish and tight dimensional tolerances, while resin sand casting handles larger, heavier components with excellent core integrity. We pour a full range of grades — grey iron (HT150–HT350), ductile iron (QT400-18 to QT700-2)— with in-house heat treatment to tailor hardness, strength, and toughness to your specification.

Service Advantages-总部接待区 1 拷贝
Material Advantages
1
We charge carefully proportioned pig iron, steel scrap, and ferroalloys (FeSi, FeMn, nodulizer) into our electric induction furnaces. Carbon equivalent, silicon content, and alloying elements are spectrometer-verified and adjusted in real time before tapping. Precise inoculation and nodulization practices ensure consistent graphite morphology and mechanical properties across every pour.
2
Every production batch is identified by a unique heat number. Chemical composition reports, mechanical test records (tensile strength, yield strength, elongation, hardness, and for ductile iron — impact toughness), metallographic analysis (graphite nodularity, matrix structure), and heat treatment charts are compiled into a traceable dossier — from furnace charge to finished casting.
3
We pour a comprehensive range of grey iron (HT150–HT350), ductile iron (QT400-18 to QT700-2), austempered ductile iron (ADI), Ni-resist, and high-Si-Mo ductile iron. Whether your application demands vibration damping, high strength with ductility, thermal resistance, or corrosion resistance, we match the grade and heat treatment to your requirements.
Service Advantages
A dedicated project manager oversees the entire process — from design review to final delivery — ensuring efficient communication at every stage.
Quotations are typically provided within 24–48 hours. Production progress is updated regularly through photos and production data, with continuous customer feedback collection throughout the project.
Full batch traceability and 24-hour response to quality-related issues ensure reliable post-delivery support.
