We present measurements of the field and angular dependence of the critical current density (J(c)) and melting line made using transport and magnetization techniques for SrFe1.8Co0.2As2 (nominal composition) biaxially oriented films. At high magnetic fields the angular dependence of the melting line and J(c) (for mu H-0 > 2 T) can be successfully scaled using an anisotropic scaling with gamma = 2, indicating a random-point-like pinning contribution.
